The guy who invented the emergency button when the market crashes

If you are one of the criminals, idealists and speculators who trade in the notoriously volatile cryptocurrency market, you may also have thought that it would be a good idea to immediately sell all your assets for fiat if prices on the market plummet.

Ilker Dagli, a systems and network administrator at Northeastern University in Cyprus, came up with a physical red button to instantly sell all crypto assets.

I decided to come up with this button because I heard from many investors that in the event of a market crash, problems constantly arise with exchanges and it is not possible to quickly sell all assets

When the price begins to fall sharply, investors cannot close their orders themselves and sell assets quickly enough to avoid losses. Because of this, some exchanges, such as GDAX, offer traders the ability to set up their wallet so that when the price drops to a certain point, the system itself will place an order and sell assets from that wallet. 

The only thing this system lacks is the red Dagli button, by pressing which you cancel all orders and sell assets at the market price. Dagli even made a video demonstrating how to use the button to sell his assets on the Binance exchange. The video says:

I had coins and orders in my Binance exchange account, by clicking a button, I instantly canceled them all and sold all my coins. I didn't have to go into the exchange system, cancel all orders manually, and then sell all my coins one by one, I just clicked a button and it happened automatically. Dagli designed the button directly for the Binance exchange, but it is compatible with any exchange that has an open API. Although, it would be better if users never needed this button.
