It is very bad that upon how this; not your key, not your coin is being preached daily in this forum, people are still falling prey to it.
Now just look at this bullshit that just took place, it is either their money has been cornered into something else or it has been stolen by someone or group of people internally, but all this is very much avoidable if people stop storing their asset in these exchanges.
Let's not be surprised that we might gets to 28th and they came up with different stories altogether, so the right thing to do is to avoid getting into such mess in the first place.
Warnings about it are everywhere, not only in Bitcoin forum, but people are victims from this bad practice are everywhere too. I don't want anyone to lose their bitcoin by bad practice with their bitcoin storage, wallets, and backups. But if they already lost their bitcoins, it's fact and can not be changed as Bitcoin transactions are irreversible.
Lost bitcoins are gift for everyone who don't lose bitcoins. Satoshi Nakamoto told us like this years ago.
Lost coins only make everyone else's coins worth slightly more. Think of it as a donation to everyone.
