High POS means big price drop, for sure. Free money is very easy to spend. but it's still a solid way for coin owners and devs to motivate people to hold his coins. Invest in MN is a huge risk(don't ask how I know ), and I am not sure How Much Is Profitable for all investor (except coin devs). Most of the MN coins which I am following they are not POS, only MN. I think those who have invested some kind of money in MN will not sell cheap because they are desperate.
