According to Kook on Twitter, Luck.io offers a referral link for users interested in crypto gambling, reminding traders to gamble responsibly. The growth of platforms like Luck.io is driving increased transaction volumes on blockchain gambling tokens such as RLB and WINR, which could impact trading liquidity and price volatility in the sector. Traders should monitor on-chain activity and token performance in response to spikes in user engagement from new referral programs, as reported by Kook (source: Twitter @kook).
