BOS developers are affected by legal policies. They also have a large number of BTC in their hands, but the price of BOS coins is still falling.
It is simply because there is very low volume and people has no interest in trading when the volume is low
as they make more money on coins that has a good liquidity. I think this is only good for long term, but it's a little risky and the reward could be very good as well if it succeed.
