Good to know that they are working on
masternodes and more
exchanges. The most important is bittrex and not too high coins for masternodes (about 3-5k coins could be good for masternode... because soon probably price will rise)
It's nice that Signatum implements masternodes.
When POW ends and POS will start?
Hybrid POW/POS starts at block 98500, in about 3 or 4 days for 1 day, then full POS.
