Well said! I want to invest on this coin, but after many technical issues I'm not sure if this is a good solution

If you know what's good for you and your money, wait till there are actually working masternodes. True, you will pay more per coin, but as it stands, you might lose easily 90% if MN's never arrive. I am down 75% on my money, so go figure.
If you are looking for masternode coins, there are more promising projects out there.
