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?
Since I start on doing signature campaigns, there are some bounties that I had saw that they reward some bitcoins on their signature bounty but it is almost a year ago. In the present times, I can't see any bounties which rewards bitcoin/s. For me, I think it is better that altcoins or tokens will be rewarded for the bounty participants instead of bitcoins, in this way, ICOs can promote their projects if the bounty hunters start trading their tokens.
