id order some miner but i dont want to wait 6 months. is there any company that could send machine sooner?
Doesn't really matter if it send now or 6 months later. Most likely you won't ROI, don't buy it unless you really know what you are doing..
why not? i mean, i understand the % goign up etc but BTC price also going up. cnnot that corelate?
If you are assuming BTC price to go up, you should just invest in BTC... when you calculate that ROI for machine, you should calculate how many BTC you paid and how much you get back....
