1. The answer will be no one knows. If those coins really can increase, the coin will increase at the right time. Otherwise, the coin will not move to any price.
2. I am not sure if Celo is a suitable coin to invest in because you already have so many good coins to invest in, why should you choose Celo? Is there any reason for that?

You can check on the top 100 coin list to find the other alternative coins to be your investment.
I think that will be better but if you think Celo is one of the good coins for your investment, you can still select the coin and start buying.
