Jimmy Song wrote a great article pointing out which factors are relevant for Bitcoin to succeed:

Funny fact on BCH: "BCH still has less transactions per day than DOGE"
In my opinion the market share of Bitcoin (compared to the whole cryptomarket) will continue to rise, especially in the long term.
Most cryptos are irrelevant, some cryptos are interesting projects which may or may not succeed and (in the case of success) will have a substantial market capitalisation (a bit smaller or bigger than today's corporations).
BUT: Bitcoin will be the ONE money of the world, a financial mirror of all the wealth in the world. That's why my long-term price prediction is around 18 million US dollar (with today's purchasing power) per 1 Bitcoin.
(Calculation: today's 280 trillion US dollar global wealth / 15 million bitcoins)

Bitcoin, not blockchain!
What's your best / educated guess?
