Its only going to get more expensive as the price continues to increase.
I just sent a BTC transaction and it cost me about $1 which is about 99 cents too much.
For this reason alone I am not gambling as much since it costs me too much to send the BTC.
You are 100% overpaying. I have been sending myself exactly on 9 May a day after you posted this and I used 1 sat/byte according to normal settings. It took me 8 hours but I do not mind,,, and if I wanted it faster 11 sats/byte was supposed to take me maximum 2 blocks to get confirmed.
That means I paid not even 1 cent. Anyway,,, if you cannot even pay $1 for gambling, then are you really a gambler? How many times you deposit anyway?
