As with any pump and dump, their play is to sooner or later trade out of the 150+ billion (80%+) premined coins. Trying to make a big enough pump to do that in todays market would be difficult if not impossible. The market won't even support selling 1k-2k USD per day. So the most sensible strategy is to keep it somewhere viable in the rankings at minimal cost, wait, and hope for a better chance to exit.
Their only hope of cashing out is a massive crypto bubble where every shitcoin in the Top 50 is getting millions thrown at it by panicked investors who aren't taking the time to research each one.
When you have 80% of the coins it doesn't take a massive crypto bubble like that to cash out 10 million USD or more. BCN market cap peaked at about 12 million USD, and that wasn't in during a massive crypto bubble, at least not the peak of one, it was well into the 2014 decline.
BCN has a better chance to pump out than some crappy #40-50 coin. It has interesting technology, pretty web sites, a backstory, and a somewhat professional and experienced crew of scammers running it.
