$BTC to $1.5M by 2030? That’s the case Blockstream CEO Adam Back is making. His argument is built around a few major factors: increasing institutional capital, Bitcoin’s fixed supply and the historical four-year cycle. Bitcoin’s supply is capped at just under 21M $BTC , while the block reward continues to halve roughly every four years. The next halving is projected for 2028. Back previously argued that $BTC could reach $500K–$1M this cycle. His latest projection pushes that much further toward $1.5M by the end of 2030. A $1.5M Bitcoin would require massive growth from current levels. Possible? Yes. Guaranteed? Absolutely not. Still, it’s interesting to think about what happens when increasing demand meets an increasingly constrained new supply.
