I am not surprised, only those who are very new to meme coins will be surprised at this, meme coins from my personal experiences are known for such drastic falls in times when there is a shortage of buyers, or new buyers to keep the momentum high, it falls, but as long as the meme coin is one that people likes and the developers know what they are doing, it will still rise back..
I actually hold no single bonk, and never did I buy or invest in it, but I've followed the project for a while now, I actually would have bought it, but I felt I was already too late into it, one meme coin I actually hold at the moment is COQ inu, and this as well have been on a decline for some weeks now, hoping it recovers soon just as bonk have recovered..
