Recently I have been reading a blog regarding the future of Zcoin walletinvester.com which claims there are chances that it may give over whelming profits in the long run, the post predicted it may go as high as $300 in the next five year compare to around $55 now giving a growth of 450% that means today's $100 could give back to five folds by the year 2022.
My opinion is that it looks promising as long as inverters shouldn't look for quick money,a long run in any crypto is always a beneficial one.
Also want to raise a point that's it's minning is bit difficult it as it takes time in transaction, require high memory ad well as computing power is also bit high,so for minning purposes it may not be the right choice.
