CyptoMining is actually a good thing!

well guys all of you know the craze of crypto coin mining like ethereum,zcash,monero etc.Now many of us does have a computer and some of us have the gaming computers with some nice power full GPU which can be used for crypto currency mining. My opinion about all this is that when you doing work on your system which is not giving any load on your gpu then it's okay to mine in that time like when you browsing,searching,doing office work which do not involves any heavy GPU work,you can mine any currency in that time and hold it. When the prices go high cash it out even that 0.05ETH will reward you around 15-20$ which is good. And please dont hate miners there trying to earn few bucks if GPU prices are rising then the retailers who are being greedy. Thank you all! :)
