I still wondering the kind of research that you are considering for a wise investor to make before buying Bitcoin, I guess you are talking about analysing the market conditions before buying Bitcoin. However, as an investor with a long term goals and objectives, you don't need to make any research about the market before buying Bitcoin, it is complex to analyze the market conditions such that an investor don't need to make investment decisions based on the market in order not to miss buying opportunities while attempting to analyze the market conditions, what every new investor needs is to acquire the basic knowledge of Bitcoin and figure out how much of discretionary income they have to invest in Bitcoin and not to wait till they learn many things since they can be doing that at the same buying Bitcoin with the dca strategy.
You still need to research the market before you buy at least that will give you more information about what happen to the market. If you buy at a high, your average buy will increase so you can make a note in your file or buy trade order.
Even if you use DCA strategy, you still need to know where is the market position, whether if that is up or down. But that will be too complicated. So we will have our own way to do related to Bitcoin investment.
The new investor should know when the time to invest in Bitcoin. Without learn more, they can not just buy Bitcoin randomly because that can make them buy at a high. Besides that, when the price is down, they can panic and worry to see their investment value will go down.
