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.
Yes 2030 is really so far away from today. Its also hard to predict Bitcoin price will 2030. But one think want to say
That we all know that a Btc halving will occur. So easily I can say that price will be boom after complete the halving.
