I bought some NMR using BLIK on Paybis last month and it was surprisingly smooth. The whole thing took maybe a couple of minutes from start to finish. I didn't have to do any lengthy verification because they let you buy up to a certain amount without itI think around $1000. The payment went through instantly via my banking app and the coins showed up in my wallet right after. The interface is straightforward and they support external wallets if you don't want to use their own. If you're used to BLIK, you'll find the experience very similar. I just went to paybis.com/buy-numeraire-with-blik/, selected BLIK, entered the amount, and authorized it through my bank app. No drama. Definitely beats waiting for bank transfers.
