stuff..
1700GHS/695$ is 0.0011/GHS and will mine less than 0.1 the first week
i don't ever buy miners with BTC but if you say that's right i'll concur.
have a great weekend.
If you buy with $ you still want to know if you will ROI in BTC so you have to compare the amount of BTC you could have bought with the amount of BTC that the miner will return.
you presume too much.
here's what I have.
a long term investment and a nice pile of paper wallets.
it is probably correct that if someone buys with $, that they are most likely so greedy to want to know precise calculations, so that they know when is best to cash out. but hey, that is indicative of the U$A.
i buy in €.
and...
you only
have to compare anything if you have OCD.
