investing in cex.io is not profitable
price of ghs is fluctuating every day
Well I'd be more worried about what ROI you actually get with the ghs rather than the fluctuating price of it.
ROI is certainly impossible but for people who invested in it to try out, they would want to sell it very soon. If the price drops ridiculously, they won't get back the same amount of what they invested. I have seen the GH/BTC dropping a lot for the last month. Even if they exit very early, they won't be able to get back what they invested.
i live example of i bought ghs @ 0.0049 GHS and sold @ 0.0046
i got 0.0004 BTC in wallet from mining and got nothing now i am trading in sites and getting 0.01 btc profit daily
