Yes, bounty hunting is still good if you were able to join those defi projects that are successful now like the uniswap where most of the users that are joining was able to get reward to which equivalent to 3 eth. I guess this is the best so far together with the sushiswap and yearn.finance coins to which market price has been pump and it hits more than bitcoin market price per coin. I think it reach to 32K USD per YFI coin and that is huge compared to bitcoin. However, when it comes to marketcap volume there is now way that other altcoins could beat bitcoin for now because bitcoin had more than 50% of the total marketcap volume in the market together with other altcoins.
