It should be noted that I am not saying that buying strategies are not important. However, I am saying that all buying strategies are the same (good) if the funds used to invest in bitcoin are discretionary income.
On the contrary not all buying strategy are good, you spoke of lump sum strategy and DCA accumulating strategy, but you never spoke of dip buying, and I can confidently say that those investors that focus only on dip buying aren't doing it the right way, because by waiting for the dip they are going to miss a whole lot of buying opportunities that may present itself in the market, so it's not a good strategy.
The best way to invest is to use either the DCA accumulating strategy or the lumps sum strategy, then if their is a dip in the market, you may decide to buy aggressively then, only if you have the reserve funds to do so, but waiting for the dip only as a strategy is a terrible way to invest in Bitcoin.
I agree with you because many investors didn't even have this in mind that, what if preventualy the dip doesn't happen or comes what should be the faith of those investors that are yet to buy aggressively all in the name of waiting for the happen, it is buying and accumulating your Bitcoin investments with DCA strategy, that always gives you the assurance of not losing all you invested on.
Investing on Bitcoin depends on the strategy you decide to use, but most preferably DCA anyone can decide on what percentage of their income which they would like to start investing from their weekly or monthly income, the can start with as low as five percent as long as it's what you can afford at that point in time, using the DCA is better than keeping your money to buy at the dip is very risky because you don't know when the dip will come or it may never come,and that is why we see no coiner or low coiner sin they wait earnestly for what they are not sure of , but buying consistently and aggressively in a normal way using the DCA strategy will give you reasonable amount of Bitcoin in your portfolio .
Lump sum give you the access to buy in bulk, which does not come regularly, its like you winning a jackpot and decide to invest all the money, instead of always waiting for such money before investing, it is better you use other strategies like DCA,buy the dip, rather than reasoning that it is only lump sum you consider ,to be better than any other strategy and you keep waiting for that huge sum of money to come before investing,you will not be able to reach your accumulation stage on time.
