What is the problem with LBC? Most of the popular payment methods have a small fee with just 1-2% difference from the exchange rates. Almost the same amount will be charged for making a trade and withdrawal from the exchange. Also there is usually an insane amount of KYC verification needed just to deposit your fiat money to the exchange account and banks (especially in my region) have a pretty high minimum limit for transactions, that are used for deposit.
Ofc some traders might ask for an ID but you don't have to go through them in order to buy or sell.
It usually depends on the payment method.
