Why has the masternode ROI only been reduced?
This seems to be common with people that don't understand how masternodes work. Every single masternode gets in a queue (more or less) for a block reward. Once you get that reward, you basically go back to the end of the line and wait till it's your turn again.
That means that the more masternodes there are, the more people in front of you are waiting for their reward. The more nodes, the less payout per day. It's pretty simple. If the nodes double from right now, payments per day are cut in half, basically.
However, let's say you buy SUCR at $.04 (like I did), the base investment is worth more. A masternode should be thought of a long term hold. Your currency is tied up and the goal is to increase the value of the currency so every payment is worth more.
