If do you believe that these coins could give you decent returns, then do it. Of course, some don't agree with you as they also have different coins to choose but I've noticed that you only invested only a few percentages on Bitcoin, I think you have to diversify it and put more funds on the valuable coins as you are aiming for long-term investment.

I understand that you are still young and that is a need for someone who can give some advice when talking about investment management. May you consider the suggestions in here but of course, the final decision is yours.
