short term focus won't work, because trying to profit from short term price movement may not be affective. as a bitcoin investor what is required of you is to be patient and consistent in accumulating bitcoin and hold. Or Less say you have already accumulated a good portion of bitcoin, all you have to do is to be patient and hold your bitcoin investment for at least 5 to 10 years or longer and you can still continue to be adding up to your bitcoin holding by DCA to make reasonable profit. So don't allow the drop in bitcoin price to disturb you, because bitcoin's value will increase, and the bitcoin price will rise over time.
This is very correct. I think bitcoin investment should already be known as a game of patience and targets. The longer it stays the better, even though there's no proof of certainty that your expectations must be met after that period. Consistency with your DCA approach is the first major step after getting a stable source of income. Financial discipline is your watchword if you must be patient to hold your bitcoin stash over a long period of time of 4-10 years. Build your emergency funds alongside and leave faith alone.
