Hey ,,I've been building btcdash.org, a free Bitcoin dashboard. Just shipped a new section tracking spot ETF flows: daily net inflows/outflows, total ETF holdings, per-fund breakdown, NAV premium/discount and Coinbase premium.

New version is live: btcdash.org/bitcoin-etf-flows/

Take a look and let me know what you think — what's missing, what's useful, what you'd change. I shipped two feature requests same-day last time someone suggested them.

Its my first circle here, and I want to know if now its the best time to sell the bitcoin and why

When it pumps they wish they had more when it dumps they wish they hadnt put so much so either way its retarded and very ungrateful and its all because money, fiat. And the gov always corrupt it.

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?
