All cloud mining farms are kind of ponzi
so all off them wiil be collabs one day
importatnt thing when you join and when you left..
Right, and you need to be able to trade your stake at any time in a real
and liquid market of both bids and asks.
i only know of 1 cloud mining service that allows instant liquidity to sell and buy on demand. That would be cex.io granted people dont like the fees or prices but they have always been around and never had a problem. I would have larger investment with cex.io if they was lower price and i like fact they have trading platform also for other coins
