What method do you find most convenient and cost-effective for converting your crypto holdings to fiat currency? CEXs, P2P, Debit Cards... ? Also curious if any new or up-and-coming techniques are on your radar.
Some have already said which method they prefer and use but I still use CEX to convert it into fiat currency. The technique hasn't changed and that's still how I do it when converting to fiat. The coins in the wallet will be sent there. From there you will choose a fiat pair that can be withdrawn directly to the fiat bank.
The reason why I use a method like this is because I cannot avoid KYC. Every exchange that operates in my country's jurisdiction, KYC is required for those who want to use it.
