At present, Bitcoin does not fully possess the attributes of a safe-haven asset, but it may become a safe-haven asset in the future.
The price of Bitcoin fluctuates greatly, and it changes faster and more frequently than the price of traditional assets. It still has certain risks. But in the long run, considering its inherent scarcity, portability, and immutability, humans are gradually migrating to the digital world. Bitcoin may need more time to gain trust and stability, and it will have the opportunity to become a safe-haven asset in the future.

Bitcoin can be used as an asset and currency. It is a store of value asset with currency attributes. Due to the high volatility of Bitcoin's price, it cannot become a widely used payment method in daily life. It is not widely accepted as a currency in daily life, but is used more for speculation. So most people don't use Bitcoin as currency, but as an asset. Therefore, people are more inclined to regard it as an asset, long-term purchase and ownership. The higher value and volatility of Bitcoin will lead to higher profits. As an asset or investment, it is indeed very profitable.

Bitcoin side chains could be developed that implement any features and characteristics of any altcoin on a side chain using BTC as collateral.
What are your thoughts on Bitcoin side chains? Is there really potential for Bitcoin to metamorphosis into every altcoin? Or are there some key limitations that could stop this from happening?

Bitcoin worked as the standard currency. There would not be enough coin to go around for each individual. Currency cannot be printed further once it reaches its limit to grow the economy , the government cannot aid in financial crisis in the same way that it can with the real dollar.
Bitcoin can't be a bubble, because it's just a ledger of transactions and a collection of nodes securely maintaining that ledger. There are no dollars and cents stored in that ledger, only Satoshi amounts.

Given that the majority of us believe that Bitcoin will increase in value over time, would u want to spend it rather than hodl and let it appreciate.

Example: Let's say I purchased a car for 1 bitcoin today but next week the value of Bitcoin has doubled meaning I was probably better off using fiat.

 I think BTC is an excellent investment and has immense opportunity to change the world, but I think these people need to educate themselves about crypto in general.  Nevertheless it's important to see congressman take a look to crypto alternatives even if the bill don't pass. We're just in the beginning, this will bring more visibility to the space

If the probability of a coin going up is higher than the probability of the coin going down (you have to make your own assessment), then it has a positive expectation, and even if risky, you will win in the long run. The volatility of the market can't be controlled,  Btc has a very high historical rate of return. As long as you can stomach swings and have a long time horizon, it's not really an issue.

China closing much of it’s Bitcoin mining is probably a really good thing for the advancement of Bitcoin that is mined with renewable energy.
It seemed that China was leading the world in mining, but was using coal power for much of it. With China’s coal powered mining ceasing, we may be able to see a quick and significant movement in the percentage of clean energy Bitcoin Mining…. I wonder if we could get above the 70% threshold that Mr Musk set to change the perception of the mining energy draw.

Bitcoin is not restricted by countries and regions. The decentralization, irreversibility, and traceability of the blockchain can solve social problems well. The emergence of cryptocurrency has provided more opportunities for everyone to explore the new world, waiting for better technology to change our lives, and waiting for the return of investment in digital assets.

I think it's because bitcoin is a relatively new concept that they have a difficult time wrapping their heads around. But they typically use fiat to make more fiat, introducing a crypto currency accepted globally undermines their purchasing power by taking away their fiat demand.

It is impossible for all governments to block Bitcoin. Bitcoin can be consumed and exchanged for other currencies, so it becomes valuable. As long as it continues to be useful, unique and safe, it will remain valuable.

This kind of thing will not happen in fact. If the governments of all countries ban Bitcoin, this will show the great terror of Bitcoin, indicating that Bitcoin will shake the country's political power, and the result is that Bitcoin is deeply rooted in the people.

As long as you invest your spare money, you can buy it anytime. Bitcoin is the perfect speculative product. Sooner or later, it will rise. It's just a matter of time. Since it is idle money, put some in the wallet and remember the private key.

Taxation can only make the price of Bitcoin higher. Taxation means that the country officially recognizes that the income of Bitcoin is legal. Since paying taxes in accordance with the law, the country has the obligation to protect Bitcoin.
