SOL

It is ok to put Sol among the three coins of your choice, as these coins have potential and are in demand in the market. But you have to think about the other two projects, because so far those projects have not been listed on the top exchange. So when it comes to investing, you have to consider everything, if you are aware of the advance update when it can be listed in the top exchange, it can be an important aspect.


For SOL, I think in parallel with you, it can be considered as a suitable investment crypto.
but for the following two cryptos, it is not very possible for me to say them. A crypto that is not on the stock market always poses a risk.
