I had invested $3500 and was doing great the first 4-5 months. You think your making all this money only to watch the difficulty go way up. I use to make a few hundred a month, now only $18 a month on DASH. I made about 60-70% of my money back.. Its a joke, you are way better investing right into the coins or go into a proof of stake coin like NEO and get paid GAS every day. JUST IMO - After about 6 months, your shit out of luck unless your getting many of those 3% codes going around, thats the only way. I finally took the correct steps and started investing in the good ALT coins like NEO, VTC, OMG, BQX and PPT and I have made 10x my money in less than 6 months. I will never invest into Mining ever again, its a waste when you can do so much better if you just spend some time researching alt coins, IMO.. Just a quick note, I spent 1.27 BTC for my 100MH of ETHER too, how am I doing..lol, The BTC would be worth about 7k today and I know I have only made a little over 2k in that contract.. Wake up and don t fall for this crap, people are constantly falling for this garbage when they could be doing so much better
