View the average Cryptocurrency Market Capitalizations on CoinMarketCap:
One way to consider a blockchain project is through its market cap. Another way, closer to the real value, is observing the activity on the blockchain. Lots of hype is responsible for "misplaced" capital in the cryptocurrency space. Blocktivity observes which project is actually being used by people, which is in our opinion, the best predictive indicator of value you can have.
If you wish to be able to spend your crypto in the everyday world, you have several options. You can withdraw from CoinBase to your bank account via wire transfer, WHICH I RECOMMEND THE LEAST. The fees are high & it takes a week to get, plus storing your crypto on CoinBase is a bad idea.
My best recommendation would be to get a crypto debit card. You will be able to use it like a normal debit card.
