I'm considering spending a big chunk on stablecoins to stake for passive income. Why should or shouldn't I do this?

So basically I'm not really getting far in life. I have a degree but I'm still not qualified for the relevant jobs in my area, so therefore I work in a bar earning £10 an hour plus tips and other gratuities but its still not that great.

I was thinking of staking stablecoins but actually putting down a significant amount of all the money I've saved up over the years. Its just been sitting in my bank because I'm to afraid to go out and spend it on expensive material things while my income is relatively low.

Binance offer 13.3% interest for staking BUSD for 120 days. This is way better than a traditional savings account and I was thinking, well if I'm not spending my money I might as well let it make more money for me while I just exist.

So what I'm asking is why should I or shouldn't I put down a lot of my money on stablecoins? Perhaps someone could tell about there experience doing so. I'll be honest its quite a daunting prospect to think a large amount of money will be locked away.

Is there also additional security i might want to consider?
