The word "investors" is the problem here.
The word is crypto"currency". The goal would be to completely replace traditional currency.
Your job pays you in crypto, you pay your electric bill in crypto, you pay your mortgage in crypto, you pay your car payment in crypto, you save in crypto, you buy your Starbucks in crypto. You sell your old game system for crypto, etc.
When you completely give up on the traditional system and value your life in crypto, your life gets better.
