it locks the 25000 so you dont spend mn collateral by accident and close mn
you must unlock every time start node
Yes, this is true. 25k bsd get locked to prevent unwanted spending and masternode disabling, unfortunately this lock also prevent masternode alias start. So to start a masternode alias you first need to unlock the collateral funds.
This thing wasn't reported in any of the guides i read about bsd masternodes, so it spent a lot of time trying to figure out what was the problem that was blocking my masternode start.
Hope this info could be useful to someone else.
