Like in Monero. I agree on that, it could be a good option, but we still need a hard cap. I also believe that Bitcoin will mostly be full no matter the variable block size.
Satoshi should have done that back in 2010, now I think it's a bit too late for a hard fork.
There were even some
serious bugs back then that would be detrimental in 2023.
BTC is ossified and there's a lot of money at stake.
Yeah, I know some people hate the hodl/investing aspect, but BTC has become too valuable, for better or worse. Nobody is gonna risk it right before BlackRock's BTC ETF.
These changes are easier when the network is smaller and each BTC costs a few cents at most...
Now you risk splitting the network in half. You need to provide some sort of guarantee that we won't have another altcoin fiasco (BCH/BSV). Who can do that? BTC Core devs? They don't control the network of miners.
It's roughly the same with IPv4: nobody could have envisioned back in the early 80s that we will have more than 4 billion devices connected online, otherwise we would have gone with 128 bits from the get-go or 64 bits at least.
