Hey Veeky Forums going to give a public service announcement cause some of you are alright. What happened with eth today provided a good lesson on why you need to be careful when margin trading. Reddit users got completely cucked because they didn't understand the implications of margin calls. Basically if a broker (in this case gdax) lends you money and you put it into crypto then they have the right to sell that crypto if the total value of it drops below maintenance margin (the amount of value you need to maintain after a trade). When a whale came and started selling like mad the price shot down and the value of peoples crpyto started to go below their maintenance margin which triggered gdax to sell it off which then caused a cascade effect to the point where gdax started selling people's eth for insane prices.
Here's a couple reddit crybabies for your reading pleasure.
Should I always keep low buy orders on exchanges with a little sum of money along with it to buy at events like the flash crash today?
Andrew Mitchell
yes
Michael Gomez
but understand that an event like this is extremely rare.
Ayden Harris
This can only happen on exchanges that have margin lending I assume, since it forcefully liquidated their accounts due to ETH's temporary low price.
Connor James
Interesting. So this means that nobody bought ETH for 0.10, right? All the profits went to GDAX.
Cooper Baker
No gdax sold the coins for fiat, the profit likely went to other whales who were in on it.
Daniel Hughes
i don't understand...
Brody Harris
Wait, I think I got it. So the price of ETH temporarily went down to $13, which lowered everyone's accounts values, triggering gdax to charge them fees to cover for their losses. Right?
Brandon Scott
...
Connor Collins
I understand that part. A whale who bought ETH during the ICO dumped 39k ether, which filled everyone's purchase orders, driving ETH prices down. RIght?
Aaron Foster
yes, gdax sold their crypto until their account value went back above the maintenance margin (often this lead to gdax selling off ALL of their coins).
Angel Diaz
so say all my eth was sold off because of this event, do they have my back?
...or am I fucked?
Nolan Davis
you're fucked
Jordan Lee
plus the margin calls, because apparently there is a shit ton of people trading on margin that shouldn't be
Samuel Reed
lmao /r/coinbase
I'm a retard who did margin calls, but I only did it with 25 bucks invested because I'm a new poorfag.
I am more retarded for not buying ETH at $16 dollars
