Coinbase could be that big in 2020, but remember that cryptocurrencies don’t need banks to hold our money. Even though more people are jumping into this cryptocurrency market, that doesn’t mean they are holding their coins on an exchange. Lots of people may be keeping most of their coins in offline wallets.

It’s true that we need exchanges/banks like Coinbase to buy and cash out our Bitcoins, but that’s all I use them for. As soon as I buy, I move the coins off Coinbase and into a paper wallet where it will sit for years.
