Why it should be limited?
Their site their rules.
Things is happening here, so without clarify anything they just raise the withdrawal amount which does not make any sense for such a big and old site.
It is unprofessional but their site their rules.
Maybe there are some technical issues in their part, I had tried it once and it is really fine for me, or maybe if the users are brand new they would not let them off if I don't give higher amounts, but I have seen many complaints recently that is why I have been out for a while in their site, but I think PM their contact service maybe there are just a technical problem and needs to be fix first.
Are you blind and unable to read posts in this topic? They don't have technical issues, they decided to raise withdrawal minimum to 0.1btc and now they decided to lower it to 0.01 on monday.
