Unfortunately, there's no event on Bitget for DEFI. Be weary of anyone introducing any event to you. It's just listing, scheduled for 31st Jan, at 10:00 UTC.
Maybe that was the event. Not sure though but seen some tweet about some rewards to traders allocated from defi team. They launch juat today and have an initial price of $1 at peak and now currently trading at $0.7 above with such volatility. This gonna be a long volatile night for them as rest of their investors seems to confuse either stake or sold some tokens as airdrops eligibility is also based on staking and activity.
