One other question, is gpu mining going to be around for a while? I know with bitcoin and some other cryptos Asic miners get built and take over the gpu's, but are some cryptos being made like ethereum to help the lone gpu miner?!
GPU mining should be around for a long time. The alt algos are designed to make it more difficult to
build an asic. There are many different algos and each one needs ts own asic to mine. And finally
there has to be enough demand for it to be profatible.
The Ethereum mining will last about 10 months. If we cannot make ROI in 10 months, we should not buy more GPU.
Do you know any other coins have the similar potential?
You only need 40 days. A r9 280 is making $3.5 a day...
So you think the price will not drop in 40 days or the difficulty will not catch up in the period?
Don't think in such short terms, especially if you're buying new equipment.
When ETH melts there will be another coin to mine.
There was no profitable coin to mine for over a year before Ethereum for most European miners.
It is better to be cautious.
