The ATH price is simply another number, for example $1300 was also an ATH back in 2017 so was any other price ($1400, $1500,... $2000, $3000,...) that was reached. We are currently sitting at ~$34,000 which is simply another number.
The only time that buying should be avoided is the bubbles. Like $20,000 at the end of 2017. Similarly $20,001 about 2 months ago was an excellent buying opportunity even though it was an ATH.
Luckily, everyone who is holding bitcoin is in green now.
However, buying for 20K in 2017 is not the same as buying at 20k in 2020, three years later.
There is an
Opportunity Cost for that money invested in 2017 and that was in red for 3 years. Additionally, many investors certainly had bad moments while in red, and emotions could have lead a lot of people to despair selling in the bear market.
about opportunity cost:
KEY TAKEAWAYS
Opportunity cost is the forgone benefit that would have been derived by an option not chosen.
To properly evaluate opportunity costs, the costs and benefits of every option available must be considered and weighed against the others.
Considering the value of opportunity costs can guide individuals and organizations to more profitable decision-making.

-70% in a portfolio is also just a number, but with consequences in daily lives...
If bitcoin goes back to 10K (which i don't think is impossible) it will be near -70%...
Personally, I think bitcoin movement in long term is upward. I think 100K might be reachable in the future. But I have no crystal ball, and I think everyone should be very carefully, especially now when in a bull run. IMO, the best time to be brave is in a bear market, not now.
