Gud evening everyone. My little take on the above topic, it all about buying of bitcoin in dca, simply mean buying bit by bit as much as your pocket can buy and holding it for a long period of time. Or buying by lump sum: buying by this method is mostly best for people that has much funds, because you target to buy when the prize drop and in large portion of it (bitcoin),and hold for long periods of time.
Take note that anyone can use the lump sum strategy to buy bitcoin either rich or poor, it does not matter the amount you are using to buy to be very big. For instance, I might be using $50 for my regular weekly DCA, and I come across funds that I am not expecting and have no budget for, maybe I was given a bonus in my place of work or traveling allowance of $500. I can choose to buy bitcoin with $300 right away irrespective of the price of bitcoin and keep $200 to buy at the dip. I can still choose to lump sum and buy with all the $500 in a go.
When you have funds to buy bitcoin like the above example that I gave and you refuse to buy bitcoin immediately you have the money and you are waiting fod bitcoin price to dip, it's not called lump sum but buying at the dip. A new beginner should think of using such strategy because it's useless for him waiting for the dip that nobody knows when it will come.
