Why not have both instead. Investing in Cryptocurrencies can be profitable but make sure you are choosing the right crypto, as much as possible scrutinize every each one of them before placing your investment. Now Coinbase Coin, to be honest, I have no idea about it yet but I just research it recently. I'd say it is worth trying though the outcome will be hard to tell, if it became successful it would be certainly rewarding, yes high risk to take but as they said the higher the risk the more profit it has.
