Best for payment would be LTC
or can just use USDT on Binance network Bep-20 or Tron Network trc-20 got low fee as well
if you compare fee you pay with paypal to LTC you can see its like less than few cent to send goes fast no limit etc like shitpal that steal for all side fee tax charge back limit acc with high amount of money in it Trust wallet is good to use on phone as well make sure to write down your 12 key so you wont lose wallet but ltc or btc best start.
