when I was a newbie I used to earn via cex.io.

I would suggest for someone new to post in here not PM someone.  And it's nothing against you.  Just in general PM's on cloud mining are more likely to try to slide in a referral vs what is best for person.

So feel free to post here... and get multiple people to anwser.   Don't go to PM for getting cloud mining info.  A lot of sites are crap is reason to be careful.

cex.io now is awful they don't deliver anything good anymore, it was decent at the beginning maybe and nothing more

right now you will never roi with them, also they maintanace fee is fucking high, it will eat all your income basically

There are a few good ones out there.  I do have a little in cloud, most of mine is hardware just as I love to tinker with them.  But I do a few trusted cloud sites with just a little.

It's only bit me once was with GAW.  I got greedy believing in them, and I lost a little.  But was a good learning expirence they are part of reason I wont invest in a cloud I don't know has hardware. I don't ever care to have anything like a hashlet or whatever in my life again.  I stick with legit cloud mining that is verified in my mind at this point.

Even I am not perfect.

They were at first... but they got greedy and started selling digital miners with nothing behind them.  I will never get what I lost back.... but at least I think there is jail-time coming - http://www.coindesk.com/gaw-faces-ponzi-scheme-charges-from-sec/ . 

And this is why you should not go all in one place.  Have multiple investments not one big one.  I was lucky I did not go crazy and dump it all in when it looked great.  I trust a few cloud mining operations but it is very few.

I think there are a few legit ones like genesis miningsweden and hashnest

I agree that its misleading although its very clearly stated that its valid only if profitable in contract along with fees. there ROI is somewhere between 1-2 years I guess but i only have very little amount. I dont know if these things scale.

Pretty much everyone got scammed by GAW, it was very well done con. Also dont go all in from start but try with small amounts like $50-100 only to start or whatever you can afford to loose.

Signs of scam

1) no daily or regular payouts or minimum payout limit or fees on small payouts
2) discount on bulk buys or options to buy with mining income(eg hashflare although they seem legit)
3) delay in support request
4) no social media presence
5) no proof of h/w (thats why i am cautious with gigahash)

and after all that there is still chance of scam if you luck is bad. Also no matter how cumbersome it is always read the contract or at least do a quick search for fees & termination.

cex.io was very popular two years ago. But their electricity price and maintenance fee are high. Their miners are too old and not efficient any more.
