As I had warned, people are dumping their Piecoin as the number of pie coins for a MN is set too high. They should have accepted the result of their twitter survey in which 50% of respondents chose 5-10k coins for a MN.
I doubt it is that because BTC has gone up again and most coins are getting a slight retracement, what are the numbers of coins needed 20k? If it is between 20 and 50k it isn't too expensive at all for a masternode. It is so cheap compared to other masternode coins still unless you are dumping or know of others first hand who dumped maybe?
