Oviously bitcoin is the king of all coin. There is no competitor of Bitcoin I think. The price is the prove for me. So it is clear that Bitcoin is the king of all coin.

Strategy pays off in the long run but you should be also looking to earn money in the short run, a strategic person should join the Marinecoin(MTC) community. It’s a community based on growth not mining or employing nefarious strategies that will drive your power bills through the roof. Marinecoin has a ICO through which you can earn 20k coins by performing tasks, and it’s repeatable every day with plans to expand it. The artificial intelligence which is the core of the coin alongside the community afterwards checks the post for proof of promotion. It’s the first of it’s kind in terms of cryptocurrencies that employs a artificial intelligence to check for true machine to machine transaction technology. It’s really innovative and solves major issues such as slow transactions since it has up to 500% transaction speed of Bitcoin blockchain and most of the time has zero fees on all transactions. The time dilution technology that it utilizes is also a new thing in the crypto market so it’s obviously a innovator. You can read up on it in their Whitepaper, I’ve already invested into it and plan to keep going as it’s one of the cryptocoins that is worth HODLing.

Bitcoin is absolutly main cryptocurrency today. Highest price, highest capitalization, highest trust and highest amount of users. It will last for years , i'm sure.

Perhaps bitcoin will be the king of all coins in the future and perhaps not, no one knows. But the fact remains. Almost 45 percent of the total capitalization belongs to bitcoin, and no matter what market fluctuations, bitcoin keeps itself confident. Bitcoin is still invested a lot of money, which means that it will continue to grow. This is a good digital asset. And his I think no one will overtake.

I think, bitcoin will still be the number one coin, because bitcoin is more advantageous because bitcoin is the first cryptocurrency and besides, bitcoin market is more stable than other coins.

I do not know the king of his coins, I do not yet understand about the coins, here I am studying and also working, I want to work on this bitcoin forum correctly, I have successfully worked on this bitcoin forum.

Indeed, bitcoin stay in it's track for many years because of bitcoin other coins created but it's not the same as bitcoin but there is one cryptocurrency that able to catch up a little bit and that is eth some said that ethereum may take the lead in the future. If you talk about ripple there's a big difference from bitcoin.
First, ripple is a centralized digital currency where bitcoin is decentralized.
Second, ripple or xrp token is a token like altcoins but xrp token is representing fiat money which means it is also base on fiat money therefore ripple or xrp token is fiat money but in digital form but there are members that tracks all tokens like a bank. Hope it helps.

i think bitcoin it the king of the king 

Very clearly the best coin is obvious, but I think it is important that this leadership is sustainable. Time can sometimes be very cruel, the champions are constantly changing in all Olympic games, and some countries can go uphill every century. Bitcoin should be used more effectively in order to continue its leadership.

Bitcoin will be the king of all coins.
That's because Bitcoin is the oldest coin in the development of cryptocurrency, the beginning of Bitcoin's creation in 2009.
During this time, Bitcoin occupies the first position in terms of the value of the price, although many emerging new coins, Bitcoin will remain superior.
As long as this is enough to prove that Bitcoin always excels, I estimate Bitcoin will always excel in the future.
