lol eth is cheap right now if i had that much to invest id buy 20k of eth 10k of btc and use 10k to build around 4 rigs to mine eth thus spreading your risk a bit.
great advice, thats what I would do too..
forget about 16 gpus per rig, but you can do 5-6 gpus per rig
My first ICO MY First Loose .. got an offer before hit rex .00099 per 1 wave for 2k investment . i refused to complete the offer seeing that 1 wave will gain more than that but now i am still holding but i afraid the price will decline to .00025 soon .
My first ICO too, so we are in the same boat.. I am just holding for now to see what will happen in the future.. now is not the time to sell
profitability has gone way down because of the whole DAO situation and there is not much POW time left.. so your ROI is questionable since your electricity is not so cheap.. the problem is we dont know much about RX 480 mining potential yet, so you cant actually calculate anything.. only speculate..
