If you want profit of holding cryptocurrency, stable coins no make sense if you are holding this.
People say that stable coin like USDT is not safe to hold, because they are not back up by the dollar, also there is news I heard USDT can be manipulated. I saw a thread that there someone asking if USDT is trusted,
Do you trust USDT?, I guess you can get a further idea about why you did not trust stable coins.
If you're going to ask me, I won't hold a stable coin at all, they seem not to be trusted due to their past trust issue.
