Mining isnt profitable now a days so most altcoins are going for proof of stake rather than mine with hardware which is costive and come with high electricity cost.
Wrong. Went through your post history and I find it interesting how one person can be so wrong on almost every post they make yet continue to keep posting.
Yes the alt-coin market is volatile, yes the difficulty is increasing as more miners enter the market, yes the barrier to start mining is rising relative to the cost of GPU's(You can't even buy a vega 64 anymore for under 800). Yet it's still profitable to mine now and will be for the foreseeable future, the market is subject to change and no one knows what will happen to crypto currency in 2018, but if you like taking risks now is the time to do it.
