I use the below three coins except bitcoin
1.Menoro (XMR)
2.DASH
3 .Etherium(Eth)

And my personal favourite is DASH because i find the potential in this coin..I believe the price of this coin will soon going to reach 0.01 bitcoin..It's price is low now but this coin is showing the potential..if it just becomes little more popular,it's price will sky rocket for sure

I use Menoro too because i heard it's easy to mine with CPU..I have not mined it yet but will soon start mining it..Currently i own few XMR that i bought with Bitcoins
