Rewritten with AI for clarity.

I don't have a deep understanding of how the Bitcoin blockchain works, but my understanding is that if a single entity, or a group of entities acting together, controlled more than 50% of the network's mining hash rate, they could potentially create an alternate version of the blockchain and have it accepted as the valid chain for as long as they maintained that majority. Is that correct?

If so, could they create fraudulent blocks that appear to show many unrelated wallets sending them large amounts of Bitcoin, even though those transactions were never actually authorized by the owners of those wallets? If they maintained control of the majority hash rate for a period of time, could they use those fraudulently obtained coins to purchase goods or convert them into USD before the honest network regained control and replaced the fraudulent chain with the legitimate one?

More broadly, could a very large data center operator, or several of the world's largest operators working together, realistically accumulate enough Bitcoin mining hash rate to exceed 50% of the network? I know the hash rate of AI focused GPUs is probably a lot lower than ASICs.

If such an attack were technically feasible, what would the approximate cost be in terms of electricity? How much Bitcoin would an attacker need to extract through double-spending or other attacks for the operation to become profitable after accounting for those costs?

Well, if it's true that for every lucky one there are 99 who cry... here I am...

I lost $50,000 of my savings, plus the pain of all the potential gains if I'd just bought that one instead of that other one, or if I'd just held on for longer. I started in 2022 and I've never managed to hold on. When I saw a 10% loss, that was already a lot; on $50,000, I was down $5... I feel like I've failed, and I'll never recover this loss, in my country it's hard to save $500 in three months.

Someone like me who has never managed to chase the bull?

I sold every other asset I owned, stopped my pension contributions, took out loans, and we even sold our old flat in Delhi.

Altogether, I have invested around $90,000 to $95,000 into BTC.

I started buying near $100k, continued as it climbed toward $126k, and added more during the recent lows.

This is risky, but it was calculated. My salary covers the loan payments, and based on my calculations, I should be able to repay everything within two and a half years.

I would not recommend anyone blindly copy this. But after years of learning about Bitcoin, money, inflation, and scarcity, this is where my conviction is strongest.

Maybe it becomes the biggest mistake of my life. Maybe it changes my family’s future.

Repay the debt. Secure the Bitcoin. Come back in 10 years.

Bitcoin's price has historically tracked a long-term power law trendline — a curve that grows at a constant rate on a log-log time/price scale.

I've built a small website to track how the price is doing relative to the trendline. Historically when the price falls below the trendline it signals a great buying opportunity. Similarly, price going above the trendline might flash a sell signal.

Nobody knows the future price, but now is a good time to turn your DCAs - now proven by a mathematical formula.
