I think that this % will only increase. Many of the current bitcoin investors are moving to alt coins as well but we should not forget that a lot of new investors are starting with bitcoins as well. I think 90 5 of the people who are entering the crypto market are starting with bitcoin investment only. I will be happy if this dominance increases as most of the alt coins have no value or uniqueness to add. They are just having a different name and trying to create hype with marketing so as to benefit from the craze of bitcoins.

Bitcoin as the first cryptocurrency, affecting the entire cryptocurrency is normal to me. Moreover, many cryptocurrencies are based on Bitcoin. This is why Bitcoin plays a role in guiding the cryptocurrency market.

That's fine, the crypto market should have a king to lead the altcoins to grow. Bitcoin is a king and is doing a great job of it.
As bitcoin rises, both markets are up and now their prices are five times higher than they were at the beginning of 2017 and the crypto market is up five times the value. That has made many people curious and invest in bitcoin. That's a positive sign for me.

This is normal it happens every time so better relax and do not panic it will back again to normal. The positive side if the bitcoin value drops the opportunity to bought another bitcoin is ther then if the value raise again then sell that also a positive sign so there is no negative sign there its win win situation, as long as the value will not reached zero.

As the first crypto currency that already has a name in the hearts of fans, do not be surprised if bitcoin controls other crypto currencies.
Society of course have put high trust to bitcoin which have proven its existence.

Definitely bitcoin is the number one cryptocurrency in the whole crypto market since it is the first to be recognized around the world. And also its success had already proven it that bitcoin over the past few years and now it is still growing. This is why that other cryptocurrency depend on the bitoin price and if were going to talk about the percentage of the bitcoin in the market still the bitcoin has it dominated. The rest percentage of crypto currency market goes to alt coins and these are composed of variety of altcoins vs the independent bitcoin. But the question is that what happen to bitcoin if the percentage will drop? Maybe the answer is that some of the bitcoin holders will invest in altcoins for them to earn especially in the upbringing altcoin with promising project to profit and will get their dividend. But for now even if the bitcoin percentage will drop nothing will change on my beliefs on bitcoin. In short I am a bitcoin believer.
