Is it good to keep money in USDT?

Could you please elaborate on the pros and cons of keeping money in USDT? I'm curious to know if it's a wise decision considering the volatility of the crypto market. Are there any risks associated with holding USDT? What about the potential returns? Would it be better to diversify my portfolio or stick with traditional investment options? I'm also interested in understanding the legal and regulatory aspects surrounding USDT. Thank you for your insights.
