Hi
I actually used Bitcoins in the beginning to sends $10 there. And Pay $5 there. But Fees killed this.
You have to use your own wallet with own private key. You can control fee want you want, but it will about scaling time to transfering to other wallet. Exchange will geting fee for transfering 50k-100k satoshi.
This Send $10 and send $5, but pay high fees nonsense is a Roger Ver misinformation shill. I still send $5 a lot and yes, lately fees were high but even if I paid 10 satoshi per byte, which was good enough for a few hours in a high mempool, I still only paid 1450 satoshi in fees. That's only like 15 cents. Most of the time I only pay 150 satoshi fees or something, which even a faucet gives me.
