Coinbase is probably the most well known cryptography exchange anywhere, especially in the US. It is a full featured exchange allowing you to send and receive many different coins from anyone. You can also send to anyone like a family member or shop online and send the coin from your Coinbase portfolio. Click here to sign up for free.
You have the ability to simply hold your coins and check on the real time pricing at any time 24 hours a day. I personally have more money in my Coinbase account than any other crypto account..it is my “go to” exchange. I also like it because you can set up regular buys like an automated savings account. I currently buy a couple different coins each week on autopilot for my future.
Of course no investment of any kind is a sure thing… it goes without saying but don’t invest rent money .. LOL
