Looking at the market chart is not really a bad idea or bad thing per say, as a matter of fact checking the market is what makes an investor to be updated on what is happening. If I may ask how will an investor know if there's Dip if he or she doesn't check the market?. Well everybody have there reasons why they check the market and the only time the market will look annoying is when one invested for a short period of time or you are gambling it but if you are for long term you need not worry because there's going to be b a pump, so the advantage of checking the market is to know when there's Dip and also keep an investor updated.
Looking at the market is not a bad or wrong idea. How can an investor buy Bitcoin without looking at the market? Looking at the market is not a bad thing for an investor but for a long term investor I don't think too much market review is a good idea. Short term or a trader is different, their main job is to review the market. But more market analysis of a trader and a long-term investor results in two types of factors. When a trader reviews the market, his skills increase and he gets a better understanding of market movements.
But I don't think a long-term investor needs to look at the market more than once or twice a day. Or even if he looks at the market three or four times a week to be aware of Bitcoin's position. But when you get too preoccupied with the price of Bitcoin, your goals can sink, which can prevent you from being consistent with your investments. I want to ask, since you are doing DCA or holding for long term and you have to buy series after a certain period of time no matter what the price, then why you focus on the market or review the market again and again? I'm not banning you from market reviews. You can review the market independently, but if you are a DCA investor I would suggest not to look too much and focus on buying.
I think looking at the market here that the op is referring to, is not just about knowing the current price of bitcoin so that you will be aware. I believe, that the looking at the market the op is referring to is the one that some investors do when they want to make bitcoin purchase. instead of them buying immediately with any price that bitcoin is at that time, they then prefer to wait for bitcoin price to come down to their satisfied level before you can buy. That's the looking at market that the op is saying is bad for investors to do. And I agree with him on that.
There are every day apps investors can always find updated about bitcoin prices, such as X, FB, Instagram etc.
If actually it is just the bitcoin price knowledge they are interested in. So there is no way long term investors won't always have knowledge about the bitcoin market on daily basis.
