The masternodes are supposed to secure a blockchain but I just keep thinking how is it sustainable? Especially when the max supply has been reached. I would not hold a MN for no rewards. I do believe mn are a good thing but I think there will be a huge price drop for coins when they reach max supply. Most people are going to dump the coins, some before the max supply and then the rest when max supply is reached. There must be a solution for this issue and I think it should be addressed now and not when the first mn coins start to reach max supply and mn drop like flies.
