My only concern is with the ongoing distribution.
Distribution in the form of rewards is too slow to matter very much. Over the next year approximately 20 million STEEM will be distributed in rewards (both content and curation rewards) and the total money supply will reach about 300 million. Under any conceivable scheme a very large portion of the 20 million will go to very large SP holders (including some who are successful posters as well). The only really significant redistribution that can possibly happen is though the market. I don't consider this a good reason to cut rewards for voting across the board, large and small alike, which is what cutting the size of the pool does.
So I'm wondering how we can address this to make potential buyers aware that with steem this trend is different from when you see it with other cryptocurrencies
Good question. I don't know of easy answers here. 95% of the stake is owned by roughly 1% of the users. There's no fast or painless way to spread that out. I guess time and confidence that things will work out longer-term is the best we can do.
