I've recently run a profitability experiment at eobot.com which has shown that the operation is a scam, it cost more than any possible profit possible. In the end there were some 110 Doge as a result, not worth anything, but to conclude the experiment I tried to withdraw those 110 Doge.
What happened? An error message popped up that the system has currently problems whatsoever and I should try later. So I did. The 110 Doge were gone from the account and never arrived anywhere else, probably in the pocket of the "company". Support does not answer.
So this is not only a cloud mining scam but a complete fraudulent operation after all.
BIG RED WARNING SIGN. Stay away from eobot.com!!!
