DEFI (Decentralized Finance) will flip banks in the future. I believe in the technology of blockchain that it will be the future monetary system. In fiat, you can print as much as you want (unlimited). The buying power of dollar right now is only 0.8% while 1 Bitcoin is always equal to 1 Bitcoin. With a finite supply of 21 million. Many pioneer holders lost their keys and some are already deceased. An estimation of 5%-10% are lost in circulation forever. Buy Bitcoin.
