If you really want to keep investing and are ready to accept all the risks then my advice is that you can choose a list of the current top coins, such as ETH, BNB, LTC,etc
Among those coins listed above, I would select BNB. Because the other two coins (Ethereum and Litecoin) have been around for a long time and a potential upside may be more muted. BNB on the other hand is an exchange token, and it has a high future growth potential. On top of that, the scheduled burn events should reduce the BNB circulating supply at regular intervals and push the value of the tokens upwards. ETH and LTC on the other hand are facing a lot of issues lately.
