I will buy altcoin, to earn bitcoin. Gambling is also my hoppy, and spend bitcoin on real life use. I will buy goods from newegg.
I think it would be better for you to grow and you get bitcoin more and you can certainly get a double advantage. you can use to invest half and half you can switch to a fiat
Altcoin investing is good, as long as you have an idea or the coin seems so promising.. That way you will earn more since you are using an altcoin, the movement of your money/bitcoin will be fast...But as I've said, choose which one is promising... Definitely avoid gambling, that would disturb your focus if you are into trading...
