Well, I'm sure you are well aware of the recent Bitcoin halving although nobody could tell actually if what price would Bitcoin going to stop. Will it touch the $20k again then dump or will it make a new ATH touching above $20k, who knows? You shouldn't be asking or waiting for some signal before you trade, it's a complete waste of time because you might miss your chances of buying or selling if only wait for them. A full time trader wouldn't do that because they are so busy watching the market.
