Yea, I do spend some time researching and looking for these coins. I'll spend a couple hours charting and researching, etc . . on both low cap and high cap coins. Sometimes, I will hear about them in another coins Slack group. But once the initial research is done, I just make sure to stay up to date on the news . . that's the easy part.
You can buy a lot of these coins cheaper than 1 satoshi of btc. It doesn't seem like it would be a lot, but with cv2 for example, I purchased about 20 million coins. that would be 1/5 of a btc if I would have bought that way. But at the time, there was a lot more volume on the ltc pairing, and the order book looked a lot easier to make a profit with. The sell walls were very slim and the buy walls were quite large.
I'm sure there are people out there who make a good living buying coins with ltc and doge, and then selling them for btc. Here is a calculator that converts the amounts.

I know its not for everyone, but there is profit to be made. When the entire market flipped to bear a couple months ago, the lower cap coins were still shining.
Thanks for your comment. I enjoy making posts and comments help me to see that this is worthwhile.
