Since it is high risk ,high reward.
As I mentioned earlier in the post
High risk does not necessarily mean high reward but to get a higher return you have to take a risk.
memecoin on Tron is not an investment but there is a demand for memecoin, this demand mostly comes from bots and a certain category of investors, this demand leads to pumping the price at a certain time and then it drops quickly, it is the definition of pump dump which is classified as fraud.
If you find an airdrop without paying here you can take a risk otherwise you will lose your money.
