all masternodes are just a ponzi .. it will definetely go scam in some days

You are entitled to your own opinion, maybe go spread FUD elsewhere, this is the only project that has a working platform even before presale and even paid for listing before it's presale. List how many of your scam mn projects as you put it accomplished this?
It is very disturbing to see how some people write anything without any real argument. Many projects can fail over time, nothing is guaranteed by anyone in the crypto world, but saying it is spam requires minimal arguments at least.
