Public trust is very large with Bitcoin with profits that are considered very cheap now and where many people speculate that the number of altcoins appears everywhere fear of their future will be forgotten because its existence is so lacking that investors who enter will be less likely, Bitcoin is king Coins, the first available in the cryptocurrency world, are no wonder people know him and want it after the hype happened late last year, so some people are waiting for the value of Bitcoin to the lowest point and buying more, the development of Bitcoin is undoubted for the future.
I strongly suspect that dominance is inversely related to the BTC price, at least when looking at these large price movements in the short-term. So when BTC returns to $7k, I'd expect dominance to drop again. But it would be good/interesting if people are losing faith completely in the particularly worthless alts like XRP.
I don't think people will understand and it will keep getting worse with each new altcoin comes into the market.
The market will keep on dividing as the fools believe every 'X' coin/token will be the bitcoin of 2020.

It is interesting that many people get stuck in that mind, but it's up to each of them, but that won't apply to altcoin to Bitcoin by 2020, and it must be realized that altcoin often comes and is useless by increasing in the crypto market, there isn't enough the power to center on one alt, it is very difficult for people to see altcoins as uncertainty.
