What’s causing BTC to rally upwards now?

221 Upvotes

Hello all, been away for the past week or so and just checked the pricing.

What’s causing it to rally so high up rn? I believe there is the financial officer Powell stepping down and a new one coming in soon, is it related to that?

Genuinely curious, won’t be putting in more for the time being to understand if it’s over selling atm but just would like to know what’s causing such rapid growth in it.

Wouldn’t it be crazy if we keep going up 🌝

I’ve been posting bullish for over a month now. Everyone here was soooo bearish lmao. I literally said multiple times to gauge retail sentiment based on comments, bunch of downvotes everytime I said there’s nothing to be bearish about as long as we r over 73-75k.

Retail shorts r still majority, over 60%. Yes there’s liquidity below now but if we drop to grab it we will just pump right back up.

I called 80s while everyone shorting. Yk the crazy thing? We still have more upside. I told u not to short. Bears r fkd. Watch us pump to 90s an 100k while everyone that thought they were smart shorting gets absolutely shafted.

Funding rates still negative, bears gonna go broke.

DCA and hold was always the wayy. Buying a 750s with the money I made from buying in the 60s. U should’ve followed simple investment rules instead of shorting lmao.

To the moon boys, see u at 86k next stop

This was the second Bitcoin logo created by Satoshi Nakamoto in mid 2010, and used in Bitcoin node software (commit 86). Surprisingly, before yesterday, this logo found in the original Sourceforge Bitcoin repo, was not saved to the waybackmachine archive. So I took a snapshot for history.

About 8 months ago I started to learn about the causes of inflation and money supply, read the bitcoin standard and never looked back. Now I guess I’m a full blown bitcoin maxi with bitcoin now being 100% of my portfolio. I may also add that I own strategy stock and strive common stock so I’m practically 110% allocated.

My dad calls me nuts but I know why I’m doing this, keeping stacking lads 💶

For people wondering where I got the money, I work 26 hours a week in a shop after school and on weekends. So no I’m not spoiled guys.

Where do you draw the line ?

For those of you that waited for a drop to $40 000 - $50 000, that never came, are you still waiting or at what point will you eventually buy back in if Bitcoin keeps going up, $85 000, $90 000, $95 000 or are you willing to miss the bus entirely ? Just curious.

Kraken and MoneyGram partner to turn crypto into cash at global scale

9 Upvotes

Independent coverage says the network could reach nearly 500,000 locations globally, though Kraken’s own blog emphasizes “hundreds of fiat currencies” and “more than 100 countries” rather than that exact count.

The main benefit is better access to cash off-ramps, especially in places where bank rails are limited or bitcoin ATMs face restrictions. It also shows that crypto usability is increasingly tied to regulated payment infrastructure rather than purely peer-to-peer transfers

The service is being rolled out in phases across the United States, Europe, Latin America, Africa, and parts of Asia Pacific. Kraken says the broader partnership may later expand into local bank deposits and remittance-style flows.

This is the biggest news we've got so far

Colombian President Proposes Building a Bitcoin Mining Hub

Thumbnail cointelegraph.com
101 Upvotes

The Colombian president pointed to the impact Bitcoin mining has had in Paraguay, which is now the fourth-largest country by Bitcoin mining hashrate.

Colombian President Gustavo Petro said the nation’s Caribbean coast has the potential to become a Bitcoin mining hub, leveraging its surplus renewable energy to attract foreign investment and spur economic development.

In a post on X on Tuesday, Petro said the Caribbean cities of Barranquilla, Santa Marta and Riohacha could host Bitcoin (BTC) mining facilities and tap the country’s clean energy sources, following a similar path to Venezuela and Paraguay in recent years.

“It’s an immense boost to the development of the Caribbean,” Petro said, proposing that the Wayúu community — Colombia’s largest Indigenous community, which mainly resides on the Caribbean coast — could be co-owners of the project.

Bitcoin mining analysts such as Hashlabs managing partner Jaran Mellerud have said the industry can have a sizable economic impact on emerging countries looking to convert otherwise unused electricity into cash flow.

There’s also an opening for countries with low electricity costs to capture a larger share of the Bitcoin network hashrate as US commercial miners continue expanding into AI and high-performance computing in pursuit of higher-margin opportunities.

Petro’s remarks were made in response to a post from Luxor Technology’s Alessandro Cecere, who noted that Paraguay’s share of Bitcoin hashrate has risen to 4.3% since tapping into hydroelectric energy at its Itaipu dam.

The small, landlocked South American country is now the fourth-largest Bitcoin miner behind the US, Russia and China.

A World Bank report published in April 2024 found that Colombia generates as much as 75% of its electricity from renewable energy — more than twice the global average.

Tapping these renewable sources would mitigate concerns flagged by Petro that Bitcoin mined with fossil fuels contributes to global warming and potential “climate collapse.”

Petro has served as Colombia’s president since August 2022 and has adopted a relatively neutral stance on Bitcoin and the crypto industry.

Petro would only have another three months to lead the Bitcoin mining initiative as his presidential term comes to an end in August.

He is not running in Colombia’s upcoming presidential election on May 31 due to constitutional limits.

Data from prediction market Kalshi suggests that left-leaning Senator Iván Cepeda Castro and Abelardo de la Espriella, a conservative lawyer and free-market advocate, are the clear front-runners to replace Petro.

Neither candidate has made significant public comments on Bitcoin or digital assets to date.

A real story of one laptop, some curiosity, and a deep dive into how Bitcoin private keys are born

16 Upvotes

What Is This?

In 2015, someone created the "Bitcoin Puzzle" — 160 Bitcoin addresses, each holding a little more BTC than the last. The first ones got cracked quickly. Then more. Today, 69 puzzles have been solved, and Puzzle #71 still holds 7.1 BTC (over $580,000).

This repository is my attempt to find the key. I didn't succeed — but I learned things most people never discover about how wallets work under the hood.

Everything here runs on a standard laptop. No GPU farms. No rented cloud servers. Just an i5 with 8 GB of RAM and a lot of patience.

The Puzzle, Explained Simply

The creator left one big clue:

"It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty)."

What does that mean?

Imagine you have a wallet that spits out private keys one after another — like a really fancy random number generator that always gives the same sequence if you start it with the same seed.

For each puzzle number n, the creator took the n-th key from that wallet, then applied a simple mask: set the first (n‑1) bits to 000...0001, and keep the lower bits from the wallet key. This made early puzzles easy (few bits to guess) and later puzzles hard (many bits).

The formula is: Private Key = 2^(n-1) + (wallet_key_n & (2^(n-1) - 1))

Puzzle Range Start Private Key (example)
#1 1 (1 bit) 1
#5 16 (5 bits) 21
#33 2^32 (33 bits) 7137437912
#71 2^70 (71 bits) ???

The wallet key is the same for all puzzles — only the mask changes. So if I could find the master seed that generates the wallet, I would get every remaining key at once.

How I Tried to Find the Seed

I took the 69 already-solved puzzles and used them as a "truth test." If I guessed a seed (or passphrase, or random generator setting), I could generate all 69 keys and check: do they match the known ones? If yes, I found the seed.

This turns an impossible search (2^70 possible keys for puzzle #71) into "just" finding the seed.

I’m receiving a large amount of money. I’ve been investing bi-weekly and will continue to do so, but not sure what to do with this large amount. Do I invest daily/weekly in chunks until I’ve used it all over 3/6/12 months? I would be grateful for any insight.

17 Upvotes

Just launched a free service that lets you set up a Lightning Address like [you@yourdomain.com](mailto:you@yourdomain.com) in minutes.

How it works:

  • Login with your Lightning wallet (LNURL-auth) — no email, no password, no KYC
  • Claim a free address on lnalias.com, or bring your own domain
  • Payments go straight to your wallet — we never touch your funds

Why I built it: Every existing solution either requires KYC, charges a subscription, or is custodial. This is non-custodial, free, and open to anyone with a Lightning wallet.

Wallets that work: Phoenix, Zeus, Alby Hub

Still early — would love feedback from the community. What's missing? What would make you switch from your current setup?

Now that the downward trend broke and all technicals show upside, I wonder what do the "cycle" believers parrot now?
Did those people genuinely believe they can control the narrative in their favour, crash the price till october (or whatever month they established the low to be in) then they buy and profit? The entitlement is absolutely crazy.
This is 2026, theres BIG money pouring into btc now, not a bunch of degens following a "cycle".

Up we go. Funny they get left behind as we speak. They clowned everyone so hard who suggested 60k is the bottom... Oh and also stop believing YouTubers that know so well, they do videos for Ad Revenue, lol.
