No matter what the current price is, people always think there will be better opportunities to either buy or sell. It's a vicious circle. I am not sure why you believe the price will drop to $20-25k. If the value drops to $25k, you will be waiting for $20k. If it drops to $20k, you might think it's better to wait until $15k. Too much waiting, and you'll miss the train. If you have money to invest and you are willing to do it, go ahead. It's the same when you are selling. If you have made some profits that you are satisfied with, dump your bags and get back in the game with the next cycle.
