@sqrrm First of all, I think we should consider the possibility that small transactions can be a **spam attack** where an ill minded hacker that wants to hurt Bisq or a Bisq hater could buy a low balance fiat bank account (i.e. below 20€) on dark marktes and use it to make a lot of small payments to trigger chargebacks from victims and cause problems to the relationship of BTC honest sellers with their banks.
Some banks, like N26, very quickly close client´s accounts without asking at the slightest doubt with suspicious transactions.
I don´t want to seem paranoid. I am aware this would be a really ill and stupid spam attack. Very unlikely I hope, but it is a possibility. Just wanted to raise it.
To answer your question I´d say that if we decide to disregard both scammer triying to validate accounts with small tx (unlikely) and the above spam attack risk (also unlikely) the minimum of 0.001 BTC proposed by @flix1 is ok, in that case the tiny security deposit, a minimum trading fee and mining fees, which will have anyway, would contribute a little bit to avoid both risks.
If on the opposite we want to minimize those risks, I´d suggest at least a minimum trade amount of 0.005 BTC and also a minimum security deposit of 0.005 BTC + mining fees (i.e. a total potential loss above $50). I don´t have any strong opinion on these figures, not really an educated guess.
