Thanks for your comment!
My opinion: the last altcoin rally was fuelled by very much ignorance and hype and this will not be repeated. The next crypto rally will be accompanied by investment and trading experts with lots of experience. That and the proposition that Bitcoin is the best store of value is why I think that the market dominance of Bitcoin will even climb much further, beyond 90%.
I personally don‘t see a necessity for litecoin, bitcoin cash or dash and think they will be eaten by Bitcoin, though I hold a small amount of each. Ripple is straight out scam.

And there are blockchains with a stable community and which are designed so that users have an incentive to hold its token, which will accrete value. I hope and think Steemit is one of it, perhaps Augur.
Concerning platforms like Ethereum, EOS, NEO I am uncertain where‘s exactly the incentive to hold tokens. Plus, there is the risk that rootstock will turn these platforms obsolete.
