You failed to mention the possibility that they are lying about it being a technical problem and that they do not have all the funds they claim to (I.e. Solvency).
Don't be naive to think that this is not a possibility.
Ponzi operators work in the exact same manner. They try to buy more time with vague excuses.
So the proper way to run a ponzi scheme is to broadcast failed transactions for all the world to see? Thanks that is good to know. The brilliance of people here is staggering.
