It's too far to predict btc position in 2030. But I think there will be many things happen with BTC from now on till 2030. And I think supply will caped if BTC still survives.
Don't be negative. Bitcoin can survive until I my self cannot. Bitcoin on 2030 will have a very big change First of this is because of the influence of technology maybe on 2030 there no fiat money and we use bitcoin as a payment. The community will become bigger and BITCOIN will be more popular to other people who don't have a connection to the internet. Many changes will occur in every year of bitcoin like today and yesterday has a very big difference.
