I think, It is really a great advantage that growth of crypto users from 1990s to 2000s has grown. This is okay if used in a proper way. But as from the study also 80% of this cryptos and ICO are being used as scams. And too much of this is also bad for us. Solution is to choose the appropriate ones. Select and eliminate. But there still great existing ICO where you can use crypto currencies better such as MyShield a decentralized anti scam platform, It can also detect fraud ICOs to save our currencies.
