Which is the best and most trusted? Cloud mining or signature campaigns?
Well in my opinion signature campaign are best and more trusted , because in signature campaign you only need to invest your time not money and you can earn coin by promoting projects apart from it you learn a lot about Crypto currency , new projects upcoming with new technology.
In cloud mining you have to invest money , and you are not sure that you will get your investment and profit amount back , because mostly are ponzi scheme. If some are not it can't be reliable as they may shutdown their services without informing.
I agree on the trust part of cloud mining but i think signature campaign doesn't guarantee a 100% of it especially when bm's accoun in a bounty thread doesn't have much of reputation in this forum, profit wise i think signature campaign is better than cloud mining.
