i have been scrolling down the bounties section and seen so many projects related to Defi and Bitcoin but i cannot understand how the new project like Defi is giving a hard time to BTC and even to other altcoins like ETH and ripple and many more?
every post and campaign i am seeing is about Defi and its making more money than others/
why?

As far as bounty campaigns are concerned unfortunately most campaogns listed that are defi based are very low quality projects that will most likely scam people, I have experienced it myself and that is why im not promoting such campaigns now. As far as comparison of defi with btc is concerned i think it is totally wrong it is like comparig apples with oranges.
