Trading anyday. You might get lucky once or twice if you bet online. But there is way more probability of losing your money and getting addicted and losing more. Its a risky gamble.

Since you mentioned 2K budget you can split into 1K for Holding and 1K for trading. Invest some money in promising ICO's. This is sure to get you some nice profits. And now is a good time since the prices are low. Like mentioned above Hodl some good Alts like NEO, XRB, ARK, ICX etc etc. Do your own research.

Also while trading don't simply put your money in some shitcoins. Make yourself thorough with some Alts and be updated with the current news so you know which coins are sure to go up.

FYI: You might have to move this topic to trading discussion.
