Wow I'm not worried about this coin's future, but I just checked the dump you guys are talking about. Unreal. 200,000 coins sold at 150 satoshi? Maybe someone hit sell instead of buy? I can't think of any other explanation.
It is not good if one person bought such amount of coins
I have to say, I own a lot of MUN now. I shall spend it in Malta in the next few years and enjoy a good holiday there.
I did a calculation, at difficulty 15 and price of 150 satoshi, the revenue is 20% of electricity cost. I do not know who is going to mine and dump.
