They didn't actually give you money though. Gifts of investments are different than a gift of cash since they can increase in value. The basis of a gift is the basis of the person who gave you the gift. This means that if when your friend bought the cryptocurrency, it cost $50 and when they gave it to you, it was worth $100, your basis is the $50 amount. If you sell for any amount over $50, that is a gain to you. Even if you sell it for the same amount they purchased it, you still have to report it to show it was not a gain.
In the investment section, you will be asked if you got the currency in a form other than purchase.
