From the beginning of the emergence of cryptographic technology, smart contracts, defi and even NFT, all aspects have changed to be more, safer and of course able to guarantee the authenticity of a work (one of which is Bitcoin = the work itself).
What aspects changed?!!!
Ever since bitcoin, the only thing the subsequent projects changed were the amount of money the creators could make from their creation with premines, ICO fundraising, scamming, shadow mining, centralization, etc. Many of the changes, specially those at protocol level, made things less secure!
I'm very curious to know what you think has changed that made things "safer".
when the price soars and falls again in a matter of minutes it can attract the attention of a country and even the central bank in that country which inevitably bank institutions and goverment will pay attention to ban the bitcoin because of this.
I have not seen a single case of a ban or even talk of ban (with no action) that were because of price volatility. Every case I've seen has been because bitcoin is decentralized and they can't control it
If banks actually use blockchain and issue standard central bank currencies or CBDCs which they call, this would be the same as Bitcoin or crypto in general?
Obviously not! It lacks three of the main principle of bitcoin: decentralization, immutability and limited supply.
2. Smart contracts, Defi and NFT. Equally a very great product in my opinion that has an important role in all aspects of course after Bitcoin.
What aspects are there? You are again speaking in vague terms without naming the "aspects".
The three innovations were able to attract the attention of many groups from the government, property industry, aviation industry, artists, musicians and many more and of course you all know.
Not at all.
It only attracted governments to fight the money laundering through NFTs, DeFi, ICO and similar tokens with different names.
It also attracted gamblers who want to participate in pump and dumping shitcoins.
Will Bitcoin remain valuable or vice versa?
Considering the fact that bitcoin is the only cryptocurrency that works as it should and the rest are either weak or useless you should know the answer to your question already!
