Many people become interested in investing in bitcoins without making an income. Before actually investing in Bitcoin, it is always better to find a source of income. Many say invest what you can afford to lose. So after family expenses from your income, if some amount of money is better to invest in bitcoins in DCA method. But it is best to invest in different sectors not only in Bitcoin. Which I am currently investing some amount of my income in bitcoins and also investing in different sectors. Even if my entire Bitcoin investment were to suffer a loss, I would not be financially broke.
No one is saying you should not invest what you can afford to lose, but what most people mean is that investing in any other coin other than bitcoin is a gamble, and it is not guaranteed that they will make a good profit in the long run as much as they can when investing in bitcoin. Bitcoin has proven to be a dependable investment over time, and this has been proven not once, nor twice. So why invest in a project where you are unsure of the outcome after waiting for so long? Investing in what you can afford to lose simply means investing in altcoins that you can afford to los.

I agree with you that holding Bitcoin for years will not prevent the price of Bitcoin from not falling, but hodling Bitcoin for years will play an important role in your Bitcoin hodling because there will be a time when Bitcoin price will never fall below $50k, and if you are still hodling your Bitcoin till that time you will not have to buy Bitcoin on a high price. But if you sell your Bitcoin before that time and you want to buy it again, you will have to spend a good fortune before you can accumulate a reasonable quantity of Bitcoin because the price of Bitcoin will be excessively high.
You are correct, but you should not be adamant about keeping the investment after you've already made a certain good profit from it, while ignoring some important life issues because you want your investment to rise above what you've already earned. Bitcoin's price will continue to rise as expected, but that doesn't mean you can't sell when you've made a good profit, especially if the market is no longer in a bullish trend and is already showing signs of bearishness, which could last for a while or be caused by the market's volatile nature. This is common after the bull run season, so you can sell some without thinking about it if you want to since you’ve already made a good profit from the investment which was the reason for the investment in the first place.
