i think that is the only way.
for mining at cex.io you will get btc and some altcoins. but that is realy not a profit. after maintenance fee you will have around +/- 0.
it is more a way to have a continual income.
that you can use for trading, to generate some profit.
You say you will get around 0 then you say you will have a continual income. It's contradictory.
I think cex.io gives you a small profit in average, 3 to 5 times less than other cloudmining services.
yes, you're right. my mistake. I have expressed myself incomprehensible.
when you buy ghs, these generate an income which is very low.
profit you make only from the date on which you get back your spending on the ghs. that can happen after an indeterminate time. but it is not sure! the maintenance fee may also exceed this income. (and even then you get an income! but from which nothing will remain, due to the maintenance cost. in the best case it results around 0)
There is a lot of speculation as to whether you get your investment back and how the company calculates its cost.
Also note the difficulty and blockreward.
You say "I think cex.io gives you a small profit in average, 3 to 5 times less than other cloud mining services."
for today and tomorrow, I agree with that. but how is it in 3-6 months?
You'll then also be able to say so?
note:
at cex.io you can also join a pool of your own mining hardware. then calculated the company no maintenance fee for you. but I do not know if that's profitable. other cost factors are then crucial...
