The stablecoin giants USDT (Tether) and USDC (USD Coin) have expanded rapidly over the past year, offering exceptional liquidity despite potential regulatory concerns. A recent Twitter debate on their safety sparked widespread discussion, with FTX founder Sam Bankman-Fried (SBF) and Tether's CTO Paolo Ardoino weighing in.
USDT vs. USDC: Safety Compared
While USDT's market cap surged from $3 billion to over $60 billion, its dominance on Ethereum has declined since May. Meanwhile, USDC's presence on Ethereum has grown significantly, with plans to go public via SPAC in Q4 2021.
A poll by analyst @AltcoinPsycho revealed stronger distrust toward USDT among crypto users. However, Larry Cermak, Research Director at The Block, argues this perception is largely unfounded.

Historical Controversies Surrounding USDT
Larry Cermak notes that safety definitions vary:
- USDC is more susceptible to freezes and lacks efficient recovery mechanisms for mistyped addresses.
 - USDT excels in usability and resilience.
 
He emphasizes that Tether complies with U.S. regulations, debunking the myth of non-compliance. Key concerns revolve around Tether's past controversies, but Larry suggests coordinated regulatory action is more likely than isolated targeting.
Market Perspectives: SBF and Tether’s CTO Respond
Sam Bankman-Fried (SBF) highlights differing liquidity profiles:
- USDT dominates secondary markets.
 - USDC performs better in primary markets.  
Safety, he argues, depends on tolerance for potential depegging (1%, 10%, or 90%). 
Paolo Ardoino, Tether’s CTO, counters:
- Tether’s liquidity survived the March 2020 crash, growing from $3B to $63B.
 - USDT maintains a 1:1 peg despite FUD, proving reliability.
