they say "send us BTC to our address, then once we receive, we send you LTC"
that is not an atomic swap
When I use the wallet, I just enter the amount I want to swap and it automatically does it. Does that mean it automatically sends to their address without me knowing?
He is saying that they require him to send Bitcoin and that when they receive it they will send the other currency. However, that is not how atomic swaps work. So he's right. Something doesn't add up.
