The entire crypto market is worth $160bn at the moment (Bitcoin: $100bn). That is less than the market cap of Visa, or equals about the market cap of Mastercard. Global gold is valued at around $8.2tn (or $8,200bn).

This is not investment advice, but _IF_ (and that's a big if) some of these coins (mainly Bitcoin and Ethereum) successfully achieve some of their goals, today's price will be extremely cheap. If not, it will probably be expensive. Do your own research and then decide whether you think they can.
