Ok everybody i bought 40x Rx 580 8GB + 10 GTX 1070. 3 months ago...
the profit was pretty cool ... now the hashrate just destroy it .. im making around 0.045$ profit by card right now ( mining ETHASH ).
I would like invest $20 000 (CAD) more ... but im afraid now ... i just need FPGA card coming ... and evrything .. what my best option ? Buy MORE GPU or look for those FPGA card ?
*** I STIL DIDNT ROI MY FIRST INVESTMENT FOR THOSE 50 GPU WILL NOT COMING SOON TOO WITH MY $20/day.
Thats a pretty serious investment. I'd suggest you read the more discussion here on the altcoin mining forum as a lot of other members have discussed the pros and cons of continuing mining with GPUs, FPGAs, or even ASICs.
Personally, if it was me with that sort of hardware, i'd definitely sell the GPUs now and try to get as good a price on it. The next question about whether or not to invest more into mining and buy FPGAs is the real question. Not many FPGAs have materialized yet and there are lots of scams so be careful.
