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?

We already saw the YFI price pass bitcoin price and it still increases while bitcoin does not want to increase higher for now. But bitcoin price will increase and start the next rally soon. But if we talk about the popularity, bitcoin will still be popular among the other coin, including Defi, because people's attention is now on bitcoin, and they want to profit from bitcoin. Only some people want to make a profit from DeFi. The DeFi attracts people to invest in their project because it can give them a short time profit, but we do not know what will happen to them. But bitcoin will online for a long time, and the price will increase from now on.
