Bittrex also did a USDT Omni to USDT ERC20 transfer/swap in 2019, as did Binance and Poloniex. Millions of users, billions in Tether. Zero evidence that this 1 to 1 par value transfer/swap was a taxable event… because 1 to 1 par value swaps are not taxable.
Any shred of evidence to the contrary would help bolster the “But think of the Tax!” argument.
How is the Maid Omni to Maid ERC20 transfer different to billions of dollars worth of USDT Omni to USDT ERC20 transfer, exactly?
