Some investors don't have a plan about their investment, they chose to buy anytime they like and sell anything they like, but they do t know that Bitcoin is not a fiat currency. It's said that most people that are new into Bitcoin lack Bitcoin knowledge which is true, some of them don't make research that's why they don't know when to buy and how to hold.
We call them newbies for a reason because they don't know anything about the industry that they're joining, only those that take it upon themselves to do their research na dem wey no go fall mugu. As a newbie e no get how you go dey just rush say you wan invest for wetin you no sabi how e dey be. If you be that type of investors, you no go last because this industry na one place wey anything wey you dey find to invest inside you go see. If you need ponzi scheme e dey. If you need Bitcoin doublers e dey, everything dey here so na for you to find the better coin na where you go need the help of community members for Bitcointalk. People here no go advice you wrongly because them been dey like you before and them dey speak from their own experience.
Although even if a crypto newbie doesn't have good knowledge of Bitcoin, if he chooses to accumulate Bitcoin with DCA method it will not be a bad idea because DCA method gives him the opportunity to buy. But even with DCA method an investor also need to be patient about making profits because Bitcoin is not a get rich quick scheme.
NCA (Naira cost average) na him sure pass say you wan invest for Bitcoin and without asking you no go know and you fit dey put all your money one time into the market but e go come dip. If you still buy like this, e no bad if you continue to dey hodl and not sell. NCA sha go increase the quantity of Bitcoin wey you for fit buy but if you no get plans of accumulation, you no get problem. The thing be say different ways dey to invest but DCA wey be NCA for Naira na him sure pass because e go give you money quantity of Bitcoin wey go mean say na more profit for you when you wan sell.
