IMO, the challenge to get to that point would be that the crypto currency be used for more than building up steem to sell it for currency. If there was more of a market where people could buy 'stuff' more easily with steem, then there wouldn't be quite the highs and lows as people buy / sell for the best outcomes.
Unfortunately, cryptocurrencies were never designed to be able to handle pump and dump schemes.
Good point. Last big Up was linked to all the money bring the crypto world by Ethereum with the different ICO. We need to see this time a new projects which will do the same.
