Sending money to someone

I love crypto, but i am mostly an holder and i never took profit till now. I imagine i will turn my crypto gain into USDC than dollars, then send it to my bank account when the moment will feel good, but i'm really ignorant when it comes to the remaining ways to withdraw money in national currency.

Anyway, a good friend of mine is always sending money to some members of his family in differents countrys. It's just little sum like 100/400 dollars, but regulary. Banks, western U, always come with some fees and he always complain. I want to make his life easier. I know there are some card from coinbase or others, but i am ignorant. If he send some crypto in order for his family change it in their national currency in Africa or Europe, what is possible for him ? Are these events taxable for him or his family ?
