In a word, it is probably that Muncoin team have actually abandoned Muncoin project since April of 2018.
Of course, someone who invested money into Muncoin project can keep their hopelessly recovery of the coin.
Personally, I believe all gone away.
sadly to say, but you maybe right.
It seems that Muncoin investors, especially masternode inverstors, will lose all their money due to such a scam masternode project.
Yeah seriously though, if you're throwing money at a project where there is zero detail about the developers, than what recourse do you have?
I mean, if you're willing to take a punt, you can always mine some, but paying in BTC for some random altcoin in hopes the masternode will take off is always going to be risky.
