RE: Was the Launch of Steem a Scam or the Only Legal Way? - Thoughts on Steem by Charlie Shrem a Week Later

To put it this way : with no new users buying Steem or SBD, the platform can't survive.

Of course it can. It's based on inflation, which is just a way of redistributing wealth. If the market cap stays the same, it just means that those who get the new money benefit at the expense of those who own the old money.
