.... 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.
