Well it is very hard for me to wait a lot of time to wait for the altcoin but i am still searching for signature campaign that reward bitcoin but it is very hard to find and also if there are some it is already full and also there are few of them actually how about you which you will choose bitcoin reward or altcoin reward?
If you let me choose, then I will definitely choose to use BTC as a reward for payment, because BTC is the most valuable coin, I think no one will reject it.
