The first name you mention is BM which is not only reliable but fast enough to handle all the bounties he hold, there is one signature campaign that pays with altcoin and rates high enough but because the OP is only a member maybe you can find another bounty, which He is still managed.
Or Op if you are reluctant to wait long to be able to sell your bounty results, you can choose a project that has been listed on the exchange so when you get paid you can immediately sell it.
Maybe what you mean is the Safemooncash signature campaign that pays with altcoins and the high rate of sr $ 80/hero $100 is quite a big payout in altcoins and unfortunately it is indeed the senior ranking members and above that they participate in this campaign, but the safemooncash campaign also exists in social media and content maybe the OP also if he has other skills he can join the campaign and even has been listed on a large exchange for example Lbank, Pancake etc.
Safehaven which is managed by Hhampuz also looks good if the OP as a member can join in the signature even though it is still not listed on the exchange I think the OP needs to try and in the future who knows soon it will be listed on the exchange.
