I would suggest if new staying with BTC. It is easiest to mine arguably and is pretty user friendly depending on miner. But some are very easy to use.
Also coinwarz is good for current BTC, but future it is not as no difficulty. Use one such as:

ethereum right now look very mineable akin to btc, so one can mine tha instead of bitcoin, the profit is around 0 $30 per month with a 970, if i've done my math correctly
