I had experience with different exchangers - some delay the payment, some have unobvious commissions. Paybis was a pleasant exception. I needed to quickly transfer bitcoin - I chose https://paybis.com/buy-bitcoin-with-revolutpay/ and did not regret it. Everything is transparent: you can see the rate, the final amount, and most importantly - really fast. The money came to the card literally in a few minutes. Now I do not even look for alternatives - I just use Paybis.
