I started doing something similar last week.

I'm not as rich as you, so I have just 0.015BTC spread across 10 coins. The thing you have to watch out for doing it on the cheap like this is that Bittrex has a 0.0005BTC minimum trade so I'm trading 1/3 of any one holding but as the pot grows, that will get easier.

You're right though, it's all about having fun!
