ETC has been lagging ETH for development for at least the last 6 months. I think it's only had a couple of ICOs and they've been scammy so they just don't have market penetration.
If this was about technology then the whole market would look different and BTS would be in the top 10, but it is as much about first mover, network effect, marketing and business partnerships as it is about tech.
Binance may be pump and dump, time will tell I guess. I still think the biggest risk is exit scam or exchange failure (Mt Gox style). It has reasonable fundamentals so while it might pump and dump a few times I'm confident the overall direction should be up.
