It's cool that they're giving away coins and all but you have to look at the conditions in which they want that to happen. For example you have to be a top "2,500 trader holding LRC" and you get 20 LRC..... you need thousands of the coins in the first place. There's no point buying these coins for a minuscule handout.

Furthermore these coins are (excuse the french) pretty shit. The best coins to hold if you're hoping for a Chinese pump are NEO, BTC and LTC.

Sure there's a hope of these coins turning out well but the initial investment is not worth it. These coins are stagnant, maybe if you start seeing an upward trend buy in. Definitely not now though.

tl;dr Don't just buy into some coins for a free payout. This is a long term game. Do your research, be smart with your money.
