Invest anda trade,
I'm not good at gambling, moreover I'm not too fond of the event.
I currently invest in a few ethereum and bitcoin with small capital, some of my capital is traded in several different types of altcoin.
gambling is obviously a losing strategy in the long run, then the addiction appears worse than speculative one, so investing in top currencies will probably be the right way, the rest, for the sake of diversity, is small amounts
