Here’s what consumers have asked with answers from DexMining staff and previous consumers.
DexMining is legitimate. It is useful and worth. I don't think you will find anything better than DexMining as far as I know of.
Most cloud mining companies are not stable. I mean these companies are there to make profit, but if the coins are not profitable to mine they lose money and sometimes they tend to pack up and shut down the company without any warnings.
I thought I would just give it a shot, but didn't realize since it was showing up in google ad that this company was scamming customers.
