it is because they are limiting the transactions for over the world and stop trading for a while but they forgot the whales those are the people who can be responsible for this changes
the whales they are diving into the dip and grabbing the opportunity collect coins as many as they can because the halving will be coming in the next few months and expect that the market price of the coins will back to huge changes
The limitation in the market was not created by traders, it was created by the space especially the exchanges and other transaction platform. It was meant to manage the panic and contain the price drop.
