Hello everyone!🫡🌻My first steps in crypto👀

I just started to understand and learn about cryptocurrency. For now, I've decided to focus only on long-term investments. #HODL 💪

I've assembled the following portfolio:
BTC 40%
ETH 20%
USDT 15%
BNB 10%
SOL 5%
XRP 5%
ADA 5%

I would appreciate advice from more experienced colleagues. What do you think? Is there anything unnecessary? Or conversely, should I add something?🤔
