$40,000 USD is nothing and it will once again hit that number anytime soon. Remember, the $40,000 USD isn't even the all time high. Look at the charts. The price always reaches a new all time high and then after few months or years, the new all time high gets beaten and another ATH takes place.
Since you are a new trader, I would suggest you to learn the market first and know about the volatility of the market. Bitcoin can be $40,000 today and it can be $20,000 tomorrow!
