Bitcoin is not an instant gateway to make people rich so you need to be patience and find a good entry price if you want to earn profit. Many new investor are losing money when they bought bitcoin last dec 2017 and jan 2018 where price it at peak.
investors who bought in 2018 for 19000 did not lose anything, if they believe that they will sell in 2022 for 100000, if not sold for 5000, and bought more for 5000 more. the main thing is not to go out and not to fix the loss and you will be in the profit.
But in that case, it will need at least 3 years to hold. Nowadays, it's rarely to see a person that patient enough to wait it for the long time, because there are so many who want to get rich and big profits in a short time. It's clear that the more days, humans are getting greedy.
