"What's in your wallet?"

What currencies are YOU following?
Do you pick them simply based on price, or do you research the technology behind it?
Did you jump on the Bitcoin train just because it is the most popular?

If you haven't gotten into the nitty gritty and started looking in to the reasons behind them below is a video by one of my faves Ameer Rosic, briefly explaining his top 5 cryptocurrencies and what technologie and purposes are behind them.

I am curious to know what everyones motivation is and how you choose what currencies to follow and buy.
