It is important to never get discouraged when something like this happens to us, after all who doesn't have a story about spending their bitcoin in stuff they did not really needed when it was cheap and now they regret doing so? But at the end what matters is that we recognize that bitcoin is going to be part of the economic system for a very long time and that it is better we get as much of it while we can, because the longer we wait in order to take action the less bitcoin we're going to get at the end of the day.
There are instances or situations in life which would really be making us to decide on selling out those coins that we do have.Its true that there's no time to regret and keeps coming back on what you had
done in the past yet this would really just resulting into more lots of stress and frustration which might be a hindrance into your possible next actions that you would be having in life or in investment field.
1 Bitcoin accumulation isnt something for everybody and it is true basing up into its value then this isnt something that you could easily get hold of but its not necessary since we could always
do in fractions.
Without a doubt the goal of getting one bitcoin is getting harder and harder, which is why for the people that are on the fence about bitcoin they need to start their journey now or they may never realize this dream of theirs, but as you say it isn't a must to buy that much bitcoin, people have made some basic calculations and if bitcoin is adopted by billions of people the average amount of bitcoin each person could have is very low, so even something like 0.1 BTC can be a huge amount in the decades to come.
