What if (most) people start operating mainly inside of the Lightning Network and don't settle their transactions on the main chain?
How secure are their Bitcoins if they only live inside Lightning?

Ultimately this depends on how long you expect bitcoin to continue its remarkable exponential rise against fiat.
It should be pretty obvious that if, for example, it goes up 500% every four years, you can just borrow against it (half the value, 8% interest, as on Coinbase), and take out a new, bigger loan every few years, while still increasing your overall net worth.
However, it should also be obvious that nothing goes up at that rate indefinitely.

So many muricans in this space who won't admit it, but their overly simplistic "CCP bad" narratives have blinded them to the fact that China has extremely ambitious green targets, and PoW, unfortunately for BTC, goes against those targets. It is not about control at all - seeing as the ledgers are public, the state can use the blockchain as a surveillance tool, but it didn't.

I'm holding BTC just so you know, but my question is why does the shutdown in China matter? I understand it temporarily reduces computational capacity and slows down some transactions because of that, but the whole thing I bought into is that this is a worldwide network and no one government can control it. So the blockchain just changes minors....right. Is there something more to this that I don't understand?

Bitcoin is digital gold, just like gold, it has the function of long-term storage and protection against the risk of turbulence. Bitcoin is digital gold, and Ethereum is digital silver. This has reached a broad consensus in the currency circle. Now it is the third digital currency that is competing for the title of digital silver. Because the creators of other types of digital currencies have reached a consensus, the status of Bitcoin is historically formed and cannot be shaken (of course, there have been some other digital currencies that have tried in history, but they end up with self-death in the end). This is not to say that Bitcoin is the ancestor of digital currency, nor is it to say how long the history of Bitcoin is, let alone to say
Bitcoin's underlying technology, the blockchain, is so awesome. On the contrary, compared with other emerging digital currencies, Bitcoin has many inherent flaws. For example, it takes 10 minutes to obtain a matching hash value for its computing speed. Around this, this is in sharp contrast to the financial operations that VISA settles tens of thousands of times per second. However, this natural malaise has increased the charm of Bitcoin, because its value lies not in speed, but in irreversible, indelible, indelible, and incapable of copying, etc., making it possible for various institutions and individuals to hold Bitcoin’s inherent credibility. Reach the extreme, because at present, no financial technology can do this, even if it can
At this point, it is certainly not distributed, but must be centralized. Once this central node is attacked by hackers, it will inevitably lead to the paralysis of the entire financial operation network.
After nearly 9 years of normal operation, Bitcoin has not had a wrong transaction. This is the proof of time. This is the charm of digital gold. It is worth holding and storing for a long time. It is as confrontational as gold. The risk of turbulence is the function of hedging.

The more opposed, the more miserable.
When it cannot be banned, you should think about how to comply.

Iran's ban on mining only lasts for 4 months, and it is not a complete ban on mining like China. Miners can still continue to use Bitcoin to trade and hold. However, the government introduced by Iran has indeed affected the miners who mine in Iran.

Bitcoin is a great innovation of virtual currency. I think it will exist for a long time. Its value lies in people's commemoration of the pioneer of this virtual currency and the commemoration of it.

Your current horizons are still too narrow. When your horizons and experience are rich, you will know that the opportunities you have missed are more than tens of millions.
This is too normal, but your abilities are limited, and you have only heard of a riskier BTC.
Wealth is the realization of your cognition, ability, and luck.

Because Bitcoin is relatively more stable, altcoins are highly volatile and risky.

Bitcoin moves from weak hands to strong hands. Good job.

No worries and great news I lost 0% of my BTC. HODLing is easy

If you really like it, why not give it a try and go after it bravely!

I think it’s really good to save money properly. If you don’t encounter anything in the future, you can only ask others for help, and you can tide over the difficulties yourself.

In time, I like to listen to cheerful ones during the day and slow-paced ones at night, and I don’t care much about the content.

Has anyone ever eaten a hairy egg? It is a chicken that hasn't come out of its shell. It has already formed. This is the most unpalatable one I have ever eaten. I vomited without swallowing it.

There are so many things I want to do, and it is not enough to just say one thing.

Shouldn't be banned, one's own body should have the right to choose, if it is banned, then there is no way out, no one is born, can it be thrown away, can't give the child the care that he deserves, and be born It is also irresponsible to him.

When I miss my relatives in particular, I will look at the pictures of myself and their relatives. If I still miss them very much, I will call them and chat with them for a while.

Go out and blow the air: standing in a wide place, feeling the vigor and simplicity of nature, blowing the air, our minds will become sober, the restless heart can also calm down, so that our mentality tends to be peaceful, and it will naturally be possible relieve pressure.
