I think even when the future is bright for crypto still we need a bridge between the traditional fiat and crypto for mass adoption and more practical uses of crypto in real life, this purpose can be fulfilled by a stable coin backed by real usd, euro or other real world currencies and it needs to be transparent and trackable.
Totally agree, global adoption of the cryptocurrency is only we need to make Bitcoin and altcoins stable because of the circulation crypto in the market is getting higher due to the increase of the users using different transactions, even people, not involving in crypto are force to buy cryptocurrency for payment porpuses, the demand will always there that always compromise the supply so I think the volatility will be lessened or eliminated if the world will embrace crypto.
