Should I convert USDT to USDC?

Should I be considering converting my holdings in USDT to USDC? As a cryptocurrency investor, I'm always looking for opportunities to optimize my portfolio. USDT and USDC both aim to provide a stablecoin solution, but there seem to be some key differences between them. For instance, USDC is backed by cash and short-term debt securities, while USDT is backed by a variety of assets. This difference in backing could potentially affect the stability and liquidity of the coins. Additionally, the fees and transaction speeds associated with these two coins vary. Could you elaborate on some of the key factors I should consider before making this decision? I'm interested in hearing your thoughts on the long-term viability of these stablecoins and whether converting from USDT to USDC could be a strategic move for my portfolio.
