How do you want to earn?
get a coin and then sell into BTC daily?
Or mining and wait until it is most profitable to sell. Also a good option, by the way.
I like Suprnova and Mining Pool Noob. Easy to start.
But before you start to immerse yourself in the topic, sort out the basics, count the benefits and read the reviews - explore cryptocurrency mining guides. Or do not bother with all this - take a chance!
