I do not know what some people are talking about when they say that 1XBit scammed them. I have not encountered a major problem with the site when making a withdrawal. There were delays but the bitcoins always arrived in my wallet.
It might be good for 1XBit to tell us what the user and the reason why he had his funds locked in the site. There are surely people out there who are trying to cheat and take advantage of the system.
