Question for Coinswap

Which chain the Nakitcoins.com and its coinswap feature supports for Tether USD (USDT)?
- Do you support TRC20 chain as the fee on this chain is very cheap if compares to OMNI layer on Bitcoin network or ERC20 on Ethereum network?
- If it does not support TRC20 chain, I hope the team will consider to support it.
- No one knows how cheap the fee on ERC20 chain will be after Ethereum 2.0 goes live.

Question for Crypto Calculator
- The site and calculator supports only 4 currencies now: Bitcoin, Ethereum, US dollar and Euro.
- Do you plan to support other fiat currency?

Thanks and have an awesome weekend.
