There will be another round for ltc, xrp and even btc ( 4 rounds in total ). If you are looking to put your name on the leaderboard, you will need the specific crypto for that but if you are not interested with it simply play and gamble as usual
They dont need to. There are alot of wagering across all currencies on chips.gg basically by separating it into specific crypto, it gives people some higher chance to win because some high roller might not have that much specific crypto needed to wager for the contests
As of now, the 1st spot currently has over $25k wagered already but dont worry there are 50 places paid for each round and the 50th spot has less than $250 wagered
