many small miners are forced to go trading instead of direct mining.
Question is, why would you trade mining shares if you can trade coins? Why not mine where it's profitable the most and trade where it's the safest.
CEX is a good example here, it's not as good in mining profits as other cloud mining sites and not as good in trading as coin exchanges.
the answer is u do them all, not all markets are goin to be profitable during certain times. you flow with which ever market is suitable for ur skill set. my personal opinion on ghs at cex, theres so many customers that are greedy ,cant add, all they do is whine and complain instead of coming up with strategy, my point is all u gotta do is outsmart this bunch. and belive me when i say im not even that much smarter than this bunch ,i make gas money here nothing special. the iq bar/standard at cex is set pretty low.
