The first time I joined this market, what I did was to spend $ 200 to buy the calculation speed on EOBOT GHS 5.0 with a five-year term. The reason I join EOBOT, is from the advertisement of another website, they say like you will make a lot of money when you join EOBOT. But when buying speed is completed, I realize that life is not like a dream, the exploitation speed is very slow and it also changes according to market prices. I did a thorough investigation to find out that EOBOT had said very well about the exploitation on their platform:
Cloud mining should be considered as a fun, recreational activity and not a source of income or investment. The above numbers reflect no difficulty increase. Investing involves risk, including possible loss of principal.

And I realized the reason that the other website inflated EOBOT is because they are participating in the "Referrals" program of EOBOT. I just want to say that I don't want to discuss whether EOBOT good or bad, should join or not. But I agree with mocacinno, it's best to use money to buy bitcoin or  altcoin.
