I've already made quite a bit of money over the past 18 months from Cryptocurrency. I have invested in Bitcoin, Litecoin and Ethereum. But, Bitcoin is still the best performer despite what some articles may say. I was never very interested in mining Bitcoin (only buying and selling) until now. The reason that I have started dabbling in mining is because of CryptoTab. It makes Bitcoin mining easy and seamless. I have installed CryptoTab for Firefox and CryptoTab for Chrome on Vivaldi and they are mining away nicely. Happy mining.
