Over 58% of circulating supply of Solaris locked in those active masternodes.
https://masternodes.online/currencies/XLRSolaris has 786 masternodes online and it has been around this number of nodes for many weeks now
I guess these guys will keep HODLing their coins for sure.
They invested into Solaris masternodes because they have strong belief on Solaris potential.
They don't have reason to sell XLRs around $3-4.
even though the market is down and has been for months now, Solaris nodes have stayed steady which is a good sign that people really support the project long term which is what Solaris is a long term project.
