OG with anything research whatever crypto you invest in on your own. See why it has the possibility to increase in price. I use Coinbase Pro, which is tied to Coinbase, but Coinbase Pro allows you to buy and sell cheaper you only pay buyer and seller fees.
For example I bought $1,000 of Cardano about 3 weeks ago and it only cost me $5 in fees. I recommend that when you purchase you use “Market Buy” so that you get your Bitcoin at that market price at that time.
Also, with Coinbase Pro you don’t have to wait for the money to get there from transfer you can invest the money before it transfers into your Coinbase pro account.
