Polkadot (dot) or all of them

Look at the picture and review the behavior of the past weeks and judge for yourself. My opinion is that the reason why all currencies go up on one day and all of them go down on the next day and repeat this behavior is this, and the price of these currencies has reached its real value, and with advertisements and main factors such as solar storms, it sometimes skyrockets. We all know its future, do you say stability or decline??
