[A good investor must be a good calculated risk taker
Risk takers are gamblers and not investors.this statement is not in anyway associated to an investor rather traders, because investors don think about risk when they invest, whey either investing weekly or monthly, they don't think about risk but invest and hope fort the outcome in the Future. Except for the traders who monitor eac move of thew market and being afraid of missing out i.e "
scalpers"
and must be very good in making strategist decision. Anyone that is waiting for Bitcoin to dip to his/her expected minimum level don't have investment mindset because Bitcoin is something that you may not possibly predict the minimum dip it will attain and as such while waiting for it to dip to your bench mark that you want to accumulate Bitcoin the price may appreciate unexpectedly beyond your target in such a way that you may not be able to strive in your investment.
Of course I agree with you that anyone who is waiting for Bitcoin to dip to his expected price may never buy because of the volatile nature of Bitcoin, because it may increase when expected to buy low. And talking about making good strategic decision in the text I bolded, of course that will be making sure you invest through weekly DCA or monthly. And making sure you don't invest above your discretion, you should be able to mitigate the use of your discretion in other not to slack behind in terms of investment. I believe in "no discretion no investment" so the only strategy iss to manage your discretion in other not to used the inappropriate and sell you Bitcoin down the river ad.
