Coinbase is one of the first places where somebody lands in her/his first steps in the crypto world, but maybe you have heard about it and you still did not sign up, or there is a (very) small chance you do not know what it is.
Coinbase is an exchange that, after a ID verification, lets you buy and sell cryptos for fiat money. Payouts are made on Paypal for small amounts, in bank accounts for bigger ones. You can pay with credit cards.
Once by once Coinbase lets its users earn some money by answering to quiz. There is a video of explanation about a new crypto, different each time. And if you are invited by me through this link, you can earn 10 $ extra for free.
