I'm sure that bitcoin is not the main thing! I have been dealing with crypto currency for a long time, but the etherium and altkoins are more often used than bitcoin.

yes in fact, blockchain would still be successful while not biitcoin as a result of several different crypto would undoubtedly replace bitcoin and would be a productive coin like bitcoin at the instant

Well, i think it can because there are lot of crypto currency that being invented now and  this is not the only blockchain that being invented. Even the price is so high, but it is very affordable for the investors to buy this compare to other currency.

The answer is quite simple. Can you survive without water. the answer is No. So it is for bitcoin. It is the transport vehicle or protocol that makes whatver we do with bitcoin possible.

Yes if the question is of survival , the blockchain can definitely survive without bitcoin, people often confuse blockchain with cryptocurrency, blockchain is the technology behind the cryptocurrency, so cryptocurrency cannot survive without blockchain but blockchain can survive without cryptocurrency.

Bitcon mainly works becasue of blockchain and blockchain in the other side exist becasue there is Bitcoin where people choose to make transactions it is a mutual relationship between the two that proved that system works for the best of the two. So technically bitcoin is functional becasue of the presence of blockchain.

For sure it will do survive even without Bitcoin because people are now getting aware of what blockchain is which makes it more popular not just because of Bitcoin alone but also with all the elements and factors involved within the blockchain that makes it survive and become more successful as time passes by. Maybe we will be thinking that Bitcoin has the one who has the says at all but we cannot rely that with absence of Bitcoin will be also the death of blockchain because blockchain is composes of not just Bitcoin but it is a wide variety of cryptocurrency together.

Why not? it is like asking "can Window 7 survive without Microsoft Word".  Blockchain is a bit like an Operating System on which Bitcoin runs. When you store your Bitcoin outside of its Blockchain (to a hardwarwallet) you are actually storing a copy of the Bitcoin which is the private keys. Same as storing Microsoft texts on a flash drive, you are storing a copy of the texts

So yes, Blockchain can survive if you can wipe out the Bitcoin but I doubt Bitcoin can be wiped out of its Blockchain.

Yes, Even without bitcoin, There are so many alts and coins in the market rather in market places, exchange and other sites, crypto currency will survive without bitcoin, It can stand alone actually, Crypto is founded by a certain community of billionaires I think, It is a sphere where there are so many community, It can survive by that sequences I think.

Blockchain technology powers the public ledger of the crypto coins, it serves as the central managing system to ensure each coin is properly documented, connected together, cannot be duplicated, the encryption and others. This technology could create any kind of coins sames as bitcoin,so probably blockchain could survive without bitcoin,its just happens that the first coin created is bitcoin and become the most popular and the most adopted coins that become known because of its value.
