Why do you think that Bitcoin will fall exactly by 30k, and not by 20k or 35k? I don't think you can get an answer here, because no one knows anything, everyone is in the same position.
We can only speculate. Personal has transferred most of his funds to stablecoins, and I look forward to further fall.
We don't know when all these is going to happen that is why it's important for watch the market Everytime so that we can sell part of our different token before the market falls. Like the whales and dolphins, they have accurate information about the market so they are always prepared to react before the market does it own thing.
