Since the price of bitcoin has down from $44,000 to $41,000, so I think a buy on dip strategy is worth considering now. I don't think such a correction will last long, especially since the halving and ETF have been the reason for the big rally. Personally, DCA isn't really needed right now, lump sum seems to be the best option.
Buying Bitcoin with a lump sum is never a bad strategy, but if you know too well that buying with a lump sum will stop you from taking care of your financial needs, don't buy with a lump sum strategy, because you think Bitcoin will never dump again, and you will see your Bitcoin even when you at a loss to solve your financial challenges. You can continue with the DCA strategy in accumulating your Bitcoin which allows you to solve your financial challenges easily while you are on your Bitcoin accumulation journey.
Investing is not a one day investment and you cannot gain everything from investing in one day. Investing is for long term, in case of long term investment only we need to invest more amount of money but not at all like that. For those who start investing with 50 dollars, 100 dollars or 200 dollars in the first situation, but starting investment is not wrong. If there was a rule in the field of investment that once an investment is made, the person cannot increase the investment, we would need more money to invest, but we can invest with a minimum amount of money and we can increase the amount of our investment if we want.
I started investing with less money now my investment amount is much higher. Investment amount increased so much not only profit from investment but I tried my best to increase investment amount and when I had money I invested in Bitcoin instead of saving the remaining money. Over the past few years, I have invested in the highest and lowest Bitcoin prices. I have invested during the highest prices, I have invested during the lowest Bitcoin prices, and I am still investing. Thinking about strategy in investing.
Of course, everything that you are saying in regards to difficulties to keep cash on the side is correct, and so if a person had invested aggressively into bitcoin, and had not maintained enough of an emergency fund, then surely there could be problems in regards to how to deal with such emergency, but of course, at the same time, as the money regularly goes into bitcoin, it may well be less of a temptation to tap into it because it is already channeled into an investment that you may well do not want to touch for quite a long time, perhaps 4-10 years or longer..
It has been my experience that different financial requirements arise when one plans to keep a large amount of money with oneself. When I bought the bike I had enough money to buy the bike in the first place and when I went to buy the bike with that money the bike showroom told me that after a month the new design bike will come and the new design bike will be good for me. According to them, I went home to wait for a month and left the money with my mother but after some time father's business needed money and then he had no other way and he spent the money on my bike. If I had bought the bike the day I went to buy the bike, but my father never sold my bike and took the money instead he used to manage the money in some other way.
Similarly, if we wait for a long time by saving money to invest, then the money will be spent if necessary and it is more likely, but if the investment is made, then we will not want to sell the investment and spend the money in another way, but we will try to arrange that money in some other way. Investment decisions should be implemented before one's state of mind changes.
