Simple math...
if u think masternodes earn better run a MN
if u cant afford one
join a shared masternode
the more MN are started the less the income advantage for them will be
the more coins removed from POS competition
its all on u u can use ur coins the way u think they earn u most
run POS
run MN
join a shared MN
via shared masternodes the MN possibility is open to anyone
