I use mine BTC but stoped because it was getting way too expensive. I have a new method that I want to share with you guys. Instead of mining altcoins I rather use wallets that give bonus altcoins when you make transaction. My bitcoin wallet gives me bonus altcoins everytime I make a transaction or recieve deposits, I get a small percentage of altcoins for all the transactions I make.
I first fund my wallet and get the bonus altcoins wait 2 - 3 days so that it won't look too suspicious to withdraw all the funds and then repeat this process over and over and get bonus altcoins that is worth a lot more and faster than mining.
The website I use for my bonus wallet is:
