I had about half a million...

In the support ticket I'd raised, they kept reassuring me their technical team was looking into it and I'd be able to withdraw next week. And then the week after. On occasion, they told me it was fixed and I could withdraw - but, of course, I never could. This was before their general bitcoin withdrawal issues and loss of public confidence so I took them at their word that it was a transient thing and continued trading.

Eventually, I realised I would probably never get them out - but dumping that lot would have wrecked the market for everyone else trying to sell up... so I just took it on the chin and stopped trading.

What the cryptocurrency scene needs is some kind of stable system where you're protected from theft and a rogue exchange can't screw you over. Losing money in unwise trading decisions is all part and parcel of the free market - but being flat out stolen from by the exchange itself is just galling.
