Someone said that $btc

whether Bitcoin will go above $30,000 or not
As long as your vision is focused 26 months ahead, it doesn't really matter
Based on BTC's mining cost valuation model, after the halving in April 2028
- Bottom valuation: 190,000
- Conservative valuation: 240,000
- Fair valuation: 380,000
- Bull market valuation: 570,000
Gold still has about 1.5% - 2% new mineral output annually
And after the 2028 halving, BTC's inflation rate will drop to 0.41%
Bitcoin will become the most scarce asset in human history
I want to ask, what is the basis for such claims? Do you just say it?
