Is market capacity a good measure for ranking cryptocurrencies and why?
If it is not a good measure, what is the best measure?

My personal opinion is that it is a measure that is easy to manipulate and therefore cannot be trusted.

I am actually of the same opinion with you OP. In 2019 when I fully got into the crypto space, there were some altcoins that was ranked in the 100 top cryptocurrency but before the end of that year, some of those coins got replaced  by other new coins which became top 100 rank in Market capacity. From my experience right from after I started investment in cryptocurrency, as the year pass by, the market capacity of some altcoins drops and other new coins take their position in ranking.  So, It's not really good metric to use because it can be very deceiving base on the fact that the the price and trading volume can be manipulated.

My felling is
Buy
Buy
Buy
Buy
Buy
Hold hold hold
How about yours?

My feelings are that Bitcoin will never go down to $5k again, despite the bear market and FUDs. It has been more than 5 years now since Bitcoin was $5k, and definitely it's not going to pull back to that price, so it's better if you start buying now and hold while you still wait for your speculated price.

Unless any terrible thing happened in the world or to the world's economy and perhaps such a pandemic lasted for more than 2 years, that's what can cause Bitcoin to go down that low; otherwise, it is very unlikely to happen.

I believe that if X integrate cryptocurrency payments, it could have a significant impact on the cryptocurrency market. It would be the first major app to do so, and it could lead to a surge in adoption of cryptocurrencies.

Besides DOGE, some people predict that some X-- token could be chosen like XRP, XLM, XDC, XYO but I think of XBT, another Bitcoin tiker[2].

So DOGE and XBT are the 2 crypto that I think of first in case Elon Musk wants to integrate crypto. Recently Elon Musk doesn't want to talk about crypto too much[3], so I'm quite worried.

Do you think X will integrate crypto? Which token will be the first choice for X?

Well, even if Musk integrates some crypto into the X app, it will likely only create some FUZZ or lead to a price surge for a short period of time. With what Musk said about making X one of the best payment gateways to even be better than PayPal, it doesn't seem that he will only integrate one coin into X; it's definitely going to be inclusive of different cryptos so that everyone can really find it favorable to send their favorite crypto. IMO, Elon Musk will definitely add Bitcoin before other altcoins.

OP, I think I read you correctly and I perfectly understand your point. What I want you to know is that the social medias are centralized platforms which operates on different rules, terms and policies. Those customer (individuals) who create accounts on those social media are only there to there to be regulated by the terms and policy of that company, if you don't agree with those terms, then don't create account. If you create account and violate any of their terms, you may put your account at risk. Centralized platforms usually have authorities that are in charge, so I don't see any confusion here mahn.

The account you have on social media is yours and can be yours for lifetime as long as you don't violate any other the platform's rules. I have been using my Facebook account for more than 8 years now and it's just there.

You are actually right with all you have said, and if your topic is comprehensively elaborated, there are still more tips that need to be prevented or done with caution for the person to actually grow their financial status.

One aspect that I want to emphasize is that some people usually spend more than they earn, while others always have the habit of spending the money they have yet to earn. The two points are really a problem for some people, which is why they don't see financial growth.

For example, imagine someone who earns a $500 salary every month, and before the end of every month, the person is already in debt of $600. After receiving his salary, he will just end up using the money to clear debts, and will still be left with $100 of unsettled debt, which will be carried over to the next month. Before that month ends, they are already on an extra loan of $400 plus the old loan of $100. It's quite funny, but that's how some people live. They spend the money that they have not yet earned, and that's a very bad habit that doesn't contribute to financial growth.

In fact, the use of native assets like Bitcoin and Ether seems to be decreasing, while the use of stablecoins continues to grow.

Overall, this trend shows that the cryptocurrency and blockchain ecosystem is very active and evolving. It also serves as a reminder that as technology and user needs change, we need to be flexible and adapt to new trends and constantly evaluate the role and place of cryptocurrencies in the future.

Are you very sure about this information? There is no data to back up this claim, so I assume it to be false. Despite the volatile nature of Bitcoin, there are still many adoptions compared to some stable coins out there. Some investors who are short-term traders of Bitcoin only use it as a hedge to liquidity and volatility. Apart from that, there are so many Bitcoin investors, more than you can see for some stable coin, and perhaps a lot of those centralized projects that really pose a risk of contract-free, and that's what most people tend to avoid.

Paper can easily be damaged as it is too fragile, and in case of unforeseen circumstances it is not reliable and will get damaged easily. Strong materials like steel, metal or iron are should be considered more and can offer more protection against damage. Also duplicate backups are necessary incase one forgets about where s/he stores them or maybe something happens.

Yeah, while paper is not really very safe, I think there are other means to support it that can make it more safe. There was a sophisticated plastic container I saw one day that has a very thick rubber skin that water cannot penetrate, and it also cannot corrode or rust because it's made of rubber.

If perhaps you write down your secret phrase and place it in such a container and bury it somewhere in your house, it can stay for years without anything happening to it.

Storing secret phrases on papers will easily be duplicated depending on how you secure the paper, like what you said, there is always a need to have the phrase duplicated on a different paper.

If this is true, this is the power of holding. Maybe there are quite a few of us who are still secretly saving the Bitcoins they bought when the price rate was still low. or even there are still some parties who still hold their Bitcoin since Bitcoin is still considered nothing. and maybe we can't imagine how much profit they can get compared to the bullish era of 2021 or the bullish era in the future.

And now it really depends on us personally whether we have started to hold on or are just delaying time. because what we get in the future also depends on what we decide today.

I cannot tell about the old holders on this forum, but I know of a few old Bitcoin holders on the Bitcointalk forum who bought Bitcoin back in 2012 and 2013, and they said they are still holding up to date. I think that to be able to hold one's Bitcoin investment for a long time, the investor must also have other sustainable sources of income that generate steady income for them. I believe that the old Bitcoin holder that I know has some other investments, and that's why they are not in a rush to yet sell their Bitcoin. There are also other Bitcoiners who had the opportunity to buy Bitcoin when the price was still $1, but ended up selling when the price got above $10, probably because they actually needed the money or they had a short vision about Bitcoin.
