Some people do not have any choice regarding lump sum. If they have $2,400 coming in per month, and they have between $50 and $100 per week that they are able to spend on Bitcoin, then maybe they are choosing to buy BTC every week, but surely if they save some extra on the side for buying on dips, maybe they don't have a lot that is set aside, so they still might not have much choice but to invest whatever extra cash flow that they are able to generate by increasing their income and/or by reducing their expenses, and maybe once in a while they might be able to get some extra cash coming in that they would have the ability to decide the extent to which lump sum and buying on dips might be preferable to just continuing with their ongoing practice of DCA.
I understand that some people don't have a choice when it come to investing a large amount of money at once. If someone has fix income and not have much extra money... they may not be able to save a lot for buy investments when the prices are low. In these cases they may have to keep investing a little bit of money regularly. But it is important to think about ways to make more money or spend less so they can save more for investing. It's about finding the right balance between regular investing and taking advantage of good opportunities in the market. And this is only Bitcoin where they can believe in.
I believe in investing in Bitcoin but I don't believe that an investor should invest a lot of money at the beginning of the investment. Suppose a person pooled his one year's income and invested in Bitcoin and I started investing with him. The difference between my investment with that person is that I invested the entire amount in bitcoins instead of saving money every month and also that person saved his money every month to invest more money in this case I would say I invested earlier than that person and my investment is more profitable. Having invested in Bitcoin before means that I have a better chance, since I can only afford to invest a certain amount of money every month, so why should I wait a long time to accumulate more money and then invest in Bitcoin?
If we delay our decision, we may change our decision. Maybe now I have enough interest to invest in Bitcoin and I don't have any financial need, I can invest in Bitcoin as easily now as I can in a year but I won't be able to invest in Bitcoin as easily. Maybe within this year I may face some financial problem due to which the money I am trying to save for investment will have to be spent on something else. If I can invest $200 every month then the price of bitcoin is changing every month and I can invest every time the price of bitcoin changes but the risk in my investment is reduced.
Suppose this month the price of bitcoin is 40 thousand dollars, this month I invested 200 dollars, the next month the price of bitcoin is 42000 dollars, then I invested 200 dollars, that is, the price of bitcoin is pumping and dumping at every stage, but my investment remains. On the other hand, if I invest all the money together, I don't get the opportunity to invest in every stage of Bitcoin price change.
I believe so much that if I can invest consistently then that investment is for me and I will definitely get something good out of that investment.
