Still bitcoin is surviving
bitcoin has been surviving all along and it has nothing to do with the news and certainly has nothing to do with its price! it is surviving because of its usefulness, security, decentralization and a lot of other things.
BTC had bumpy ride as the price goes. This is not the first drop in price and certainly not the last. It is just the matter of believeing in new technology. If you the technology is useful and revolutionary then you will hold.
Blockchain technology is the most secure way for transaction. That's why bitcoin is getting popular day by day
I don't think you can say that 'blockchain technology' is necessarily secure. Bitcoin is pretty secure because there's a very large tangible cost that needs to be paid in PoW for someone to try a double spend attack. But that's just Bitcoin. That's not something that is inherent to 'blockchain'. It's just a data structure.
Yes, good point, because blockchain does not necessarily equate to bitcoin. The tool that the mechanism uses does not always amount to the same solution. Because one bank uses SWIFT payment system or IBAN does not make it as robust as another one. They have different operating standards which differentiate them from one another.
I think there are lots of potential vulnerabilities in blockchain itself still, but bitcoin is more secure because of how it structures the data and has higher standards in terms of requirements for approval. This, consequently, also makes it somewhat slower than other crypto currencies, but in the end it is worth it.
