I'm in the same as you. I've been dumping a few hundred a month into BTC, ETC and LTC for a few months and at the time of writing (BTC is currently hovering around 14k) my investment is worth 3x what I've put in.

While I'd love to see crypto disrupt the current financial system, it's just fun to be a part of the ride. I see this as play money. It's fun to track the price up and down.

It will have to do a repeat of the 2012-today run up for me to make huge money - something I'm not expecting - and unless it does this, I'll not be cashing out. If it happens then awesome, if it crashes tomorrow then I've spent a bit of money for a bit of added excitement in my day.
