Everybody knows about Bitcoin.
Why would X and Y but bitcoin at such high prices ? ($8000-1000) while BTC started from few cents.
Why would wall street join BTC ?
We wont see 20k lvl again. 10k is history.
Why? because limited quantity of bitcoin in circulation! and an increase of demands and users believing in it
the same principle for commodity and substance in real life. more demand low supply, market price will increase higher
the only thing that make bitcoin becomes cheaper if it becomes useless and worthless for investment or currency
