Exactly mate, every investment needs an understanding about it before even doing it, the impression that one mustn't have good knowledge about Bitcoin before investing on it is wrong cause if the investor doesn't know much about Bitcoin, how would they know how or where to buy Bitcoin from, how would the investor know where to save and which is the best place to save Bitcoin, how would the investor even know which strategy is best for accumulating Bitcoin? All those questions are what the person who made that statement should've put into consideration before saying that. Infact before you go into anything that involves money or finance you must have a good knowledge about it so you'll be able to do it properly, for instance if JayJuanGee didn't have good knowledge about Bitcoin investment, how would he have been able to teach people about it and how to go about it the right way but from his post, you'll understand that he's an experienced investor and someone with a deep knowledge about Bitcoin and how to invest and accumulate it over time, that's why you won't see him advising people to go into trading or other risky ways of accumulating Bitcoin, therefore an investor must be very knowledgeable about Bitcoin before investing on it. Saying it a waste of time is misleading cause the investor would be wasting their time when they invest wrongly and end up losing what they're trying to accumulate.
