How Is Bitcoin Blockchain Different From Altcoin Blockchains?

[hd49728]

blockchain itself is not a "software" it is a database. as the name suggests it is "a chain of blocks" which means blocks of data that each is linked to the previous one like a chain.
considering the fact that a very large percentage of altcoins have copied bitcoin, their blockchains are exactly the same.

I don't know whether we can have a site that has all stats on total hashrates of each cryptocurrency network. But even without such a site, I believe that the total hashrates on bitcoin network makes it totally different from any other cryptocurrency (altcoins). It is the fact that altcoins might never pass through to beat bitcoin. In the crazy years of 2017 and 2018, people talked about the flippening of Ethereum or Ripple that have never happened and even in such period, I doubt that their networks' total hashrates were higher than bitcoin network's hashrates.

bitcoin and blockchain is different from each other because bitcoin is a digital currency, while blockhain is a databases scattered in all parts of the world that is why even if one goes down there will be no interuption that will occur, blockchain is important for digital currency to run, correct me if i'm wrong

I think its more correct to say that block chain is the digital transaction ledger where all transaction appear transparent.
Bitcoin is the digital currency which this digital ledger support.

Is that view okay?
