The transaction fee of Bitcoin is still a little bit high compared to some altcoins like litecoin and Bitcoin cash. This is why so many platform would prefer to use the litecoin and bitcoin cash because of their low transaction fee.
Bitcoin transaction fee is not considerable when you want low transaction. You need to allow your Bitcoin earnings to accumulate to higher amount before you request for withdrawal. However I love to use bch since it is easy to afford.
Compared to Bitcoin Cash or Litecoin (both hard forks of bitcoin), bitcoin has higher transaction fees. However, when you compare with transaction costs associated with traditional finance (bank charges, bitcoin fees are very small.
I won't even mind paying the transaction fee of Bitcoin twice than taking what PayPal charges for any amount of transaction that you're carrying out with the payment processor. PayPal is the most greediest PayPal processor company that I have used their services.
