For DeFi, I think it will continue to gain popularity over time as centralized exchanges are now developing their own decentralized wallets for DeFi activities. This support could contribute to DeFi's growth.
As for Bitcoin, as long as the German and US governments reportedly continue to sell, it will be challenging for Bitcoin to reach $100K USD this year.
I think DeFi have been quiet for quite some time but with the help of the CEX, they might shine again. DeFi is not new but I think CEX is only sticking on their principle, though they decided to try something new this time and make their platform a hybrid one by having that feature there. Whether you are CEX or a DEX user, I think it's a win-win situation.
About BTC, I see on why its price have dumped hard. The price last time isn't really high for them to sell, though they are only an investor just like us and sometimes they also need money but there should be a time that they will stop doing it, so there is still a chance for the BTC to reach a hundred thousand dollars.
