I respect the fact you guys are doing the best to make your service popular but i dont see any reason why myself and others will leave long-existing bitcoin tumbler like Blender.io that offer service fee from 0.5% to 2.5% and make use of a mixer company created last year and offer see ice fee of 0.5% to 5%.
But for the review i also recommended loyce and Darkstar
None of the experienced members around will go ahead and „risk“ their funds - even if it’s not a lot - in order to do this. You may reconsider, choose trusted members and send them the „bounty“ upfront so they can test and review. That’s just my two cents though.
This has happened before, and I can assure that no experienced member will risk their
BTC to try out the platform, If OP indeed needs honest reviews from reputable users, he would have to send them the rewards first or at least make use of an escrow.
If the trust member of the forum wanted to do the review, i dont see any reason an escrow have to be involve cause trust member will wang to paint his account red because of 0.003BTC.
