base on my own opinion. i think bitcoin is so much special than other cryptocurrencies because bitcoin is the first that created and the tree of all cryptocurrencies around their. and such as bitcoin is the king of all the cryptocurrencies.
I believe that bitcoin is so much special than the other cryptocurrency because the price of bitcoin is very high compare to all cryptocurrency and i am sure that only one cryptocurency can also have high price like bitcoin do is the ethereum, and bitcoin is the best among the rest that's why it is more special.
In the market, maybe the value of cryptocurrency is all, is right?
But honestly, the value of Ethereum does not need to reach which value the Bitcoin price has reached.
Because as long as the market cap of Ethereum and the total transaction hash of Ethereum network more than Bitcoin, the No.1 cryptocurrency will be Ethereum, not is Bitcoin like now.
BTW, Bitcoin has not anything special in my eye, only Satoshi Nakamoto relinquished the rights to change Bitcoin's system, making it became a system dependent on the decision of the majority of users in the Bitcoin network.
