EOS is a scam?
How? He made Steem. There are many people using steem. How is that a scam?
He made bitshares. Look at market cap / history. How is that a scam?
he is moving on to new projects, as he should. His EOS ICO is far from scam; ico->dump people will not buy it, they can not wait 1 year to dump

So, not a scam. But very long term.
