Wait for the dip, i guess it could go as low as the last big dip. That one lasted for about 10 days.
Actually, we hit a three bottom dip and it happened couple of times so if you're planning to buy bitcoin just have a target price to buy or just buy little by little so you can still buy if there will be another dip. With this, you can maximize every dip that will occur.
That is an effective strategy and you should follow it because when you will buy bitcoin on a dip, you are not sure if the dip will continue and create another dip or it will just go up again so you should not go all in and buy little by little until it starts to go up and that is when you will start to make money.
