Bitcoin Bagger: Learn how to bag bargain Bitcoin

Bitcoin was at $81,659 when this page last refreshed at 08:18 BST, down 0.72% over 24 hours, using CoinGecko's figure. It's refreshed every five minutes. If CoinGecko doesn't answer we try Binance, then DeFiLlama, so check the source printed beside the time on the price card. The charts are a bit different: they're drawn from daily closes, so for most of the day they'll trail the live number slightly.

Our current estimate is 19 Mar 2028, at block 1,050,000, which is 77,268 blocks on from where the chain is now. It's a rough date. We take the block height from mempool.space and assume blocks keep coming at the recent pace of about 9.6 minutes each, and that pace shifts whenever miners plug machines in or switch them off, so expect the date to wander by a day or two. When it does arrive, the reward for each new block drops from 3.125 to 1.5625 BTC.

The routes we track are US spot ETFs, which hold 1,487,109 BTC between them, shares in the 153 listed companies that keep Bitcoin on their balance sheets, and mining shares. They behave quite differently, because an ETF follows the price less its fees, whereas a treasury company's shares also move with its debt and with how many new shares it issues. Most UK brokers don't offer the US-listed ETFs to retail customers, which is why our ETF tracker also covers the exchange-traded products listed in London and Europe.

Compare the ways in

Each one is the net money that went into or out of the US spot Bitcoin funds on a single trading day, in US dollars, once new shares created and old ones redeemed are netted off. On 20 Oct 2026 the total was +$29.6m, and over the last five trading days it came to +$207.0m. We take the numbers from Bitbo, which publishes them after each US session, so the latest day shown is normally the previous trading day.
