[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 each move of the market and being afraid of missing out and sell pips i.e "
scalpers"
Yeah you are correct, however there's still a little risk involve when you are holding Bitcoin for a long term, know one can be too sure what will happen to Bitcoin in future we all know Bitcoin is highly volatile in nature and that is the little risk that is involve but the risk in trading is more high than that of an investor who is accumulating and holding for a long term.
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 misusing your discretion. I believe in "no discretion no investment" so the only strategy is to manage your discretion in other not to used the inappropriate and sell you Bitcoin down the road.
Yeah you are correct, we need to use only our Discretionary income to invest in Bitcoin, using money meant for settling our bills to invest in Bitcoin is very wrong, we also need to have an emergency fund, it will help us during time of emergency there by preventing us from dipping hands into our Bitcoin investment.
Why always worry about risk when investing for a long time purpose remember that bitcoin is not shitcoins bitcoin has great potential when held for long talking about risk in bitcoin might discouraged people who has interest to invest in bitcoin making them believe is a bonzi scheme and this can be misleading unless you want to gamble with bitcoin that bitcoin may seems risk to you but not for time investors nothing like risk, traders are the ones who sees bitcoin to be risk and not investors approaching bitcoin in a manner that that it won't affect your personal needs have discretionary income accumulate Bitcoin gradually using the DCA method and hodl for a longer period of time.
