Most amazing with you OP because still 15 years old have ideas and good decision investment for the future on cryptocurrency, I don't know what have I did trough 15 years old. Maybe play with my friend and still do not know about investment assets between cryptocurrency or other kind of investing. Maybe I can give you way with cryptocurrency trading for the future by investing on top potential coin, invest on BNB, ETH and BTC only as long term investment and you can get much profit later when you pass school or have 20 years old. Not worry with BTC, BNB and ETH are best coins investment for the future.
