Re: eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20
There won't be any cost impact at all.
Good to hear that.btw are you using other third party exchanges for aggregated pool?
You've misread the whole statement. There is no part in the whole paragraph where we guarantee someone won't be able to confiscate your coins. We only guarantee a good risk-score in *our* aggregated pool.
I know you can't guarantee what happens on some other website aka exchange 
Let me clarify what I wanted to say with one real life example I heard from our local board recently.
Guy was doing some trading and he was using centralized exchange for this purpose, he accepted coin from other guy on his exchange account and everything was fine in 2021, other guy received fiat money in this trade.
Centralized exchange was used in this case to avoid getting coins that are connected with some hacks, scams, etc, and nothing was wrong in 2021.
One year later in 2022 he gets a letter from authorities that those coins are coming from scam, and in 2023 (two years later) police confiscate totally different coins from this guy.
They make the rules so they can do whatever they want
Had the same thing happen to me. It's vile.
