Everyone has their own thoughts.
Investing in Bitcoin is indeed quite promising for the future and there are those who doubt that, but what must be understood is that the profits that will be obtained are quite commensurate with the risk, meaning that if we invest in Bitcoin with a small amount of funds, we will not get large profits.
I don't mean to be greedy in taking profits, indeed we have to be realistic but there is no harm in taking big risks for big profits, especially if we only use a small amount of funds to invest.
Is a very wrong strategy as an investor by thinking that you
will not have much profit on investing on Bitcoin with a smaller amounts on a regular basis, however I disagree with you because there is no way you can compare the risk involved on chasing profits to holding because there is no risk involved on holding but however the only interpretation or reason why most people always like to take advantage of the price is actually because of greed and also I would advise you that if your strategy is by risking big to get big profit it will be wise for you to change that narrative because so many investors has end up destroying there investment portfolio because of greed, so perhaps just like @JayJuanGee mention earlier there is no way you can compare the profit you would make if you hold to the little profit you would have by chasing profit.
I think you are misunderstanding him, what he is actually saying is that your profit in bitcoin is proportional to your risk level. That is to say your amount of money you invest in bitcoin will determine the level of profit you get from bitcoin at the end of your maturity date. It's a very simple mathematics, someone doing a DCA of $50 weekly will not have the same level of profit as someone who is doing $200 DCA weekly if they are both having the same maturity date. Provided your financial situation can cater for you doing DCA with some bigger amount of money then go for it. DCA is not just for people who are doing $10 or $20 weekly or monthly. There are people who are also doing DCA with $500 and above weekly or monthly.
