Blockstream co-founder Adam Back posted on X: "In my view, if we transition gradually into the sudden phase, the influx of new users will intensify the adoption effect, rendering the 'diminishing return' theory ineffective, and will rise to the top of the S curve, much like the $200 trillion addressable market that Bitcoin pioneer and first BTC recipient Hal Finney (@halfin) estimated in January 2009. Bitcoin's S curve may now enter a steeper period." Back added: "My guess is that the trend of diminishing returns may break upwards in the next 2-5 years."
