As you are you have to be careful. And invest wisely. Since you have 2 BNB you can invest on few coins. Then you won't lose. Because investing on one coin is a loss. It is more likely to happen. I hope you understand.
the right answer is bitcoin. choosing bitcoin for long-term investment is the most appropriate choice.
It's good to give advice to others but it also has to be a decent recommendation and with good reason.
choosing the wrong coin and or choosing a coin that is centralized and controlled by the owner of the coin has a risk that may be rather high. because the centralized coin will crash whenever he wants because all control is already in the hands of the owner of the coin.
and i will reverse your words to be careful investing in centralized coins.
