Thanks to u/drubid I've also tried the Harmony's Viper Exchange for DeFi things (swap/liquidity/staking). The whole experience was smooth. BUT probably it wouldn't be so easy for the first-time-DeFi/DEX users (Step-by-step guides: https://noise.cash/post/143k66mr) I sent 267 ONE coins to MetaMask, bought VIPER for half (130 ONE [kept 7 for tx fees]), and provided liquidity. Then staked those LP tokens to earn more VIPER tokens because the current emission rate is quite good. Already earned 0.04 VIPER Tbh, I feel like this can only yield its benefits in the long term only because the Harmony and Viper swap aren't popular at all and VIPER tokens from LP mining are 95% locked. But overall the experience was great because it was really cheap (fraction of ONE coins is about $0.13 itself). Looking forward to BCH smart contract and DeFi platforms to be able to put into good use my BCH #DeFi
