This was my suggestion. She will need a cryptocurrency exchange account, to offramp the crypto you send her into Baht in a bank, but it shouldn't be difficult to do, and it will cost you PENNIES to send her money.
Also, she can avoid offramping via a bank by exchanging the crypto for cash with a trusted P2P partner. (Charge will be 1-2%) This is a not uncommon side-business for people all over the world.
