And what if one just picks an available offer? Are they so bad?
They can be taker and pick one of available offers to start trading. It saves their time but maybe a given rate does not suit their interest.
In addition, depends on account and payment method, trading limit can be low to 0.01
BTC. It is explained by a general low trading volume on Bisq exchange too.
What happens if the person buying bitcoin does a chargeback after the bitcoin has been released from the multisig address?
Bisq only supports payment methods for which chargebacks are not easy (e.g., this is why PayPal and credit cards are not supported). But there is still a little chargeback risk with banks. If a bank executes a chargeback after the BTC has been released, there is nothing a mediator or arbitrator can do.
Bisq's goal is to make this scenario as unattractive as possible, using three primary mechanisms:
- Account aging requires newly-created fiat payment accounts on Bisq to have lower trade limits, and those limits are increased over time.
- Account signing requires higher-risk payment methods to be signed upon verifying the integrity of a trader before account aging kicks in. Until such accounts are signed, buy limits are set to 0.01 BTC.
- National currency payment methods which are found to be used for chargebacks are quickly removed.
