No one can know when is the best time to buy. When Bitcoin reached $ 20k and $ 3k I read the same thing. Make your own report, if you think Bitcoin has potential for future growth, buy it. Never invest based on anyone's advice.
Yes, because buying at least someone has a certain goal and when we just follow the advice of others then basically everyone has a different plan, so try to have notes and good plans to do because any price at the time of purchase becomes a calculation to make next plan after buying.
