Cardano has not released the main-net where DApps canl be built but it has already $1B marketcap. Irony is that Cardano may never have successful DApps

It was never meant for social dapps. They aimed for business uses. In fact, I would say they are more government friendly than most other crypto projects. For example, New Balance using the chain for authentication tools.

I think Tron is more similar to Steem in terms of what they are trying to attract.

Interestingly, Crypto multimillionaires, Roger Ver, Andreas Antonopoulos, Charles Shrem, Max Keiser, Dan Larimer, @block.one CEO, Brendan Blumer all has Steemit accounts

With the exception of Dan, those people are not here for the Steem network. Even @fluffypony, lead dev of Monero is here, but they aren't active and about. At the end of the day, more than one of those guys listed are "Bitcoin maximalists". They are not interested in seeing this space flourishing.

They were more than likely here to see if they could make more Bitcoin by selling STEEM. Some of them maximalists consider alt projects "scams that allow their founders to make more BTC."

Probably, if a multimillionaire or couple of them buys 25M Steem from the market, then Steem will probably reach its landmark marketcap

I'm not as optimistic. Our whales and STINC will increase their selling and we are back to square one.
