I agree with what you say, even though it's not entirely true. what we can do with coins fully in control is in our hands. but, we cannot control the market price of the coin itself. I mean, we can't raise and lower the price of every coin we have.
No need to spend all your coins. They will certainly grow in value and this will give you a good profit. You only need to wait a bit and wait for the growth of the entire crypto market. That is what will give you a good growth momentum in the future, which will be able to provide you with a good profit and a return on your investments.
