That's not how it works @vynchy. You don't just hire people and they work. People need to be hired and trained which is going to take a significant amount of time. You also have to consider the server upgrades that may affect the website. I used to work in data centers, and scaling projects could take hours, if not days.

There are tons of security issues that need to be thought about as well. At the companies I worked for, there was only a certain threshold where we could come in and upgrade people's systems because of business hours. However, these exchanges operate 24-7. How do you scale a system like that and keep it running at full speed?
