.... did research to make sure each company had a valid POOL.
YET EVERY DAMN CLOUD MINING SITE TURNED OUT TO BE A PONZI! And I lost ALL my coins.
Cointellect - hashie - hashprofit - scrypt.cc - cloudhasher - probably 1 or 2 others.... ALL SCAMS.

i am wondering what kind of research you did that you couldn't find out that cloudmining is a risky business. and i am not familiar with all the cloudminings you listed here but i know a couple of them and they have been evading providing any proof of reality of their business which means they had no hash power to mine with.
Thats why this is lesson for us must be learned and the one reliable source of info if we need something is all in here and so by that we must avoid cloudmining because all of them are ponzi-scheme theirs no such mining investment for today is legal running since difficulty of blocks are even more higher thats why anytime they could run and turn scam.
