Cryptocurrencies are not about getting rich, it's about global changes. Blockchain will be used in more and more industries. And it's either you are in or out.
Most of the world's population is still out and it will remain so.
Crypto is still a thing for a selected few, not for the masses.
And as long as we keep on having people supporting scam ICOs, we will never have global acceptance because crypto will have a bad reputation.
It's not like people choose to support scam ICO's, they wouldn't knowingly support a scam and put their money at risk.
Some of these ico's just have amazing whitepapers, websites and an army of shill accounts.
