Which coin is good for mining now ?
It depends on your GP but the most popular is still ETH. But if you are not comfortable with it always check the stats on
https://whattomine.com/Consider ethereum will move to the POS casper and it has stated in the whitepaper if the block reward will be reduced from 3 ethereum to the 0.6 ethereum and it will not be a good choice for long-term. Lisk looks another good option for OP. But it looks like OP needs a new coin to make it worth to be minted.
I thought they will change to POS from POW. But i will choose ZEC,ETC to mine coinse it is way more comforable to mine tokens. Do you suggest any GP to buy? i use GTX1080 and i really wanted to buy more. if you could assist me.
