I cannot agree with your comment. I think there is no need to do market research before investing. When you do research to invest. Then if the market does not come in your favor then you will wait to invest. This is not the right method of investing. It seems that you do not have proper knowledge about the DCA method. If you were aware of how the purchase is made through the DCA method then maybe you would not have thought of doing market research before investing.
It is funny when I hear people talk about making market research before investing in Bitcoin, sometimes I see this as unknown discouraging factors to this potential investors, why will anyone want to put him or hersself on such pause mood when there's available method that can be used to invest in Bitcoin as your pocket allows, my question to this people is, must the market favour you before you can buy? There's something people don't understand about Bitcoin investment which is volatility, I think it is even the reason why DCA method exist, DCA method is a calculated idea because the originators of Bitcoin investment understands how volatile Bitcoin is and how discouraging it tends to be when one decides to wait till the dip before they can buy that's why they initiated DCA method which gives every investor the leverage to buy Bitcoin at all time without minding the price or researching the price, I think people should rethink and stop doing a research that may not favour them or may be keeping them stranded without achieving their goals in the said investment.
