my answer is absolutely yes..
i stopped collect bitcoin in earlier this year because i have to focus on my work, just a few month and now as we see surprising bitcoin rising price is extraordinary.
i regret having sold my btc before, if i know i will keep it mine

but it's not too late i will focus to collect and save btc again and i'll keep it as a long term investation.

Yeah no one was expecting that much high price from the bitcoin because the bitcoin is increasing more and more I can do the value of the bitcoin will be more than this till the bitcoin will grow and all the people will see how fast the bitcoin will help the people to be the rich person and how fast it will be the best currency I can see the value of the bitcoin will help all the people and the price of the bitcoin will be 45000$ in the future.
