What coin or token LOST you the most money? and when ?

I see lots of threads about making lots of money on a specific coin/token, and those are great and provide inspiration to many.

This topic is about when things don't go your way, and you end up losing money.

Hopefully people will share stories of big losses as freely and openly as stories of big gains.

As for myself, I personally do not have any big losses (or gains)... but I have plenty of stupid trades I am guilty of making.

I am the proud owner of over 800,000 NEF coins, bought for the rock bottom price of 1 satoshi each on YoBit, or about $25.
Why? Good Price, nowhere to go but up..
Plus this coin had been over 1 satoshi the day before, which hasn't happened since or for many months before my trade.
It was indeed a very stupid trade.

Great examples would be buying high and realizing that was not wise, and ultimately selling at a lower price than you bought. And then of course after taking the loss you'd watch the price go back up day after day....

Please share the most you've lost on a single coin...

And if you sold at a loss, what's the price of that coin today and would you have been better to keep holding?
