Doing further research, I understand USDT may collapse in the future so I think I’ve made a mistake by buying CTSI paired with USDT
Would you guys advise I need to do anything or am I getting confused and CTSI value will be CTSI value regardless of if it was bought as CTSI/USDT or CTSI/BTC?
Don't get too confused Op, if you had bought CTSI/USDT pair, what it simply means is that you sold your USDT for CTSI in exchange and now what you own in your portfolio is the CTSI coin and no longer USDT and this is how it works, But if you want BTC, you should trade on the CTSI/BTC pair, meaning you will liquidate CTSI for Bitcoin and would no longer have CTSI coin in your portfolio but BTC.
