Welcome to bitcointalk, oceancucumber.
After creating a hidden service, an altcoin, and a mining pool, you may try more complicated projects like gambling sites and exchanges.

An exchange is actually on my list of projects. Once I get my plate cleaned off a little, I'll start creating one.
Sounds great, but you really need to test it as much as you can if you plan to use it to open a business. I have heard multiple cases of people making tiny mistakes in coding their sites, and losing significant amount of bitcoin.
maybe you should change your sig?
