Being able to know and how to read the current market price in Bitcoin chart is not a bad thing but as an investor it is not necessary because knowing how to do all that won't add anything to you and going dip to learn all these, I will say or believe you have an ulterior motive because an investor doesn't really need to learn or know all... Moreover, knowing how to read Bitcoin charts won't make you know how your business is doing because anytime you entered your portfolio you can see everything there very bold and clear as a matter of fact, a long term investor is not even suppose to give a shit about how his or her portfolio is doing and you are sounding more like a trader because investors, long term per say don't really need these stuffs.
it is true that reading and analyzing market prices certainly does not hurt, even in my opinion it would be better if we could read price movement charts and others. but yes, for long-term investors, of course they will not focus too much on price charts, it will not be a problem because long-term investors are certainly the safest thing for them to harvest it someday after a long period of time.
Yea, it's true that reading and analyzing the price chart does not hurt, but your analysis should have no part to play in your decision in investing in Bitcoin because reading and analyzing the price chart are for traders not investors, our duty as a Bitcoin investor is to buy it once our discretionary income is available regardless of it price as at then, because right now Bitcoin might look very expensive in the eyes of many, but it's actually very cheap and will be a bargain in like 10 years time coming or more, so the best decision now is to buy and accumulate a very good stash of it, because that's what going to determine how profitable and successful you might be in the future.
So in as much as you are reading and analyzing the price chart of Bitcoin, let it has no role to play in your decision making when buying and accumulating Bitcoin because waiting or trying to outsmart the market is fruitless and a total waste of time and effort, so it's best you act once your discretionary income is available.
