The chart only focused on BTC. And it is almost impossible to understand others seriously. But there seems to be a few more performing coins. (Of course, we can't understand which coin is available because the chart data is not very healthy.)

charts like this are not meant to focus on individual coins, it is meant to show the long term movement of all the coins and for that, it is obvious that even though in short term altcoins may perform well or in some cases better than bitcoin, all of them in the long run are going down and lose value without an exception.
for example during 2017 and the pumps, there were many coins that went up a lot more than bitcoin did but they have all lost all that rise, and not just that they also lost more than just that rise. they went below their starting price.

What an excellent chart. 

It is the perfect chart to illustrate that Alt coins has a shelf live and that the majority of them start with a hyped up launch and then a frenzy period where people are buying coins in the hope of making a huge profit and once they realize that the Alt coin is going nowhere, they start dumping it and it ends up going down and eventually dies. 

It also shows that Bitcoin is totally different from Alt coins and that it does not follow this hype cycle. The reason is simple, Bitcoin is actually used in the real world and it was not just developed to make a quick profit. 

No need to debate which coin is the king of crypto. Out of all those years that passed, bitcoin has been performing well throughout the years. Bears or bulls, bitcoin remain to be the most picked crypto and this will never change as of now.

I made the right decision to stick my investments when I was still a newbie to bitcoin rather go along with the hype of alts. Although there were alts that provided massive returns to its investors but still I'm satisfied that I've stayed to bitcoin.

Do you think Libra can compete with BTC in the struggle for the throne?

Too many data entries are shown in the same graph. We see a lot of colors, but there is no data to compare and compare. For example, I follow the light yellow line. It looks pretty good. If I had known which coin it was, I would like to compare the date, the total quantity, etc. It could be compared.

Of course, Bitcoin is still the most important cryptocurrency. However, it would not be enough to see the price to read the data correctly.

I don’t know how on earth you understand the chart that you posted here, I am not a chart lover and I don’t think I even need any chart to confirm what you said. Everyone knows that bitcoin has always outperform most of the coins that we have in the market because it is still a coin that is the most popular being the first, the most reliable and may also be the last of its kind in future when it is being accepted as the main global currency.

The future of bitcoin is still very bright and I know that the gap between it and Ethereum will still be like x5 of what it is now in future, so any investor that would like to invest in this king of coin should better do that now before it becomes really too late, although anytime is still good to invest, just that it is best to get the coin at  cheaper rate.

a long time ago, bitcoin has always been the top crypto. in addition, the world is also more aware of developments in bitcoin compared to other cryptos. it is evident from the price, we know that the price achieved by bitcoin today, starting from the number 0. because of this, bitcoin is the king of crypocurrency.

Let’s be honest here. Bitcoin is the only crypto that brought the crypto-currency game into the mainstream. The chart clearly shows that although Bitcoin suffers a slump at times, it still out-does the other coins in the long run.
A new crypto is introduced practically every day in the market but it is clear that every person that deals in crypto always has a little more trust on Bitcoin than any other crypto currency out there.
There is no doubt about the fact that the newer cryptos do a little better in the beginning and that is merely because of the fact that they’re new introductions and no one knows which one might strike gold. Other than that, Bitcoin is clearly the winner and in for the long-run.
