I’m not keying to the idea in this statement because for me it’s very contradictory as to what the goal of a true bitcoin investor should be. The goal of every bitcoin investor should be to invest for the long term goal only, and not short term profit making mindset. Anyone who’s in for the short term mindset or goal is not worthy to be called a bitcoin investor, but he or she is a trader. I think this two things needs to be differentiated when it comes to bitcoin accumulation and investment. No doubt that every investor seek to make a significant success of high ROI, but that’s not to say that bitcoin investment guarantees profit making and at such people should come to bitcoin investment with profit making mindsets especially quick ones. Bitcoin investment is a long term investment and at such anyone desirous to go into it should set the long term goal of consistently or perhaps persistent accumulation of bitcoin and hold for the long term purpose, anything other than that is no longer investing, but trading.
And when you talk about avoiding regrets, then you’re being emotional about the market fluctuations and such mindset or people who gets too emotional and panic to sell  when they noticed a little downturn in bitcoin price are traders who are only in for a quick profit making mindset and that’s what differentiate traders from investors. A true bitcoin investor don’t panic to sell nor get emotional about bitcoin fluctuations or whenever there’s a little downturn in the market price, rather they will seize the opportunity to accumulate more bitcoin stash and add to their portfolio and hold for the long term goal.
