Hi All. I think like a mepistol. A 0.1% or 0.2% change will not deter traders from trading in Bisq.
In general, the possibility of receiving a refund on a bank transfer is not very high, at least in SEPA, unless fraud has occurred. The limitation of amounts per operation also prevents us from getting into serious legal problems.
However, the risk that all accounts of a centralized exchange are stolen and their data going to the hands of criminals is a certain risk, which has occurred many times, also with Localbitcoins. Even if they are not stolen, the data will pass to all kinds of government agencies.
Another risk, this daily, that affects the centralized exchanges, is the way they manipulate the price, either by means of boots, or by other means. Can anyone tell me who controls daily that they do not manipulate users’ access to push the price in the direction appropriate to their interests ?. Or that they are not applying a slight delay to the entry of operations to supervise them all for their own benefit ?.
If the code of those exchanges is not public and audited daily, it is an act of madness to invest there. Even what seem more respectable: https://www.coinbase.com/legal/user_agreement make it clear that they do not guarantee continuous access. An access that usually fails to the detriment of users, rarely the other way around.
In any case, the payment systems susceptible to fraud in Bisq should continue to be improved, as this yes may deter traders. Maybe Bisq could put a 1 month withholding on BTC withdrawal, after paying with any of these means, to avoid refunds. After all, BTC are usually acquired to speculate and people may not care to wait in such cases. It would also open the door to new forms of payment.
In the comments of the Reddit article, cash by mail is also mentioned. This has also been proposed here https://forum.bisq.io/t/request-cash-by-mail-in-usd-and-cad-markets/1866/29
