Also one of the factors that always affect an investor from accumulation of Bitcoin is always expecting the Bitcoin price to dip before they could start accumulating, considering the price movement of Bitcoin waiting for the dip may not be advisable because you could be waiting for a long time and the price is still not dip.
By doing lump sum buy, buy the dip, and buy through DCA. I have done this for like a week now and I have seen the difference from my previous approach.
There is a situation where you will find yourself, with these three strategies you can be able to start accumulating your Bitcoin. For instance, if you want to buy Bitcoin now, you will be afraid to buy because your mind will tell you, you are buying it at a high price, and you would not want to do that. But if you divide your money into three parts, and immediately buy with a lump sum as the Bitcoin price keeps on an upward trend, keep the second part to buy Bitcoin when there is a dip in Bitcoin price, and the third part is to buy Bitcoin through DCA that will help to control the volatile part of Bitcoin in your holding. These three strategies will help people not to miss out on Bitcoin when the Bitcoin price is too high because if you want to use only the DCA strategy you might not be able to accumulate the quantity of Bitcoin you want on time.
It seems you have another way of buying in Lump Sum because from your quote you are trying to say that Lump sum is good when the Bitcoin price is high but however on the contrary I don't think is the best way to Lump sum because the quantity of Bitcoin you could get if you Lump sum when the price is higher will be a bit small compare to dip, so however is mostly preferable to Lump sum when the Bitcoin price is a bit dip because that's the only way you can get a good amount of Bitcoin.
Also you don't necessarily need to use all the three strategies or rather method before you can start your investment because as an investor having too much strategy can affect your accumulation process either negative or positively so perhaps you could just focus on the DCA and Lump sum if you have the funds instead of three strategies.
