For me its the same. This is a one time chance. It you stop investing you will probably regret it later. Don't be feared
Never stopping to buy bitcoin should even be every investors watchword or motto.
Every time is good to buy. Peaks, dips, corrections etc as long as there is available funds to buy at that time.
It may look pretty expensive at that moment, but only time will tell if it was worth it or not. Like you said, it is either one buys now or regret when the value is much higher later on. Just in this past few weeks, so many people have regretted.
Although bitcoin has a good potential to increase its price more and more but I think still for a good trader it is too much important to have good study about the market. he must know all the good and bad aspects and should according to the situation. I do not think that it will be a good decision to invest your money in a business without have a good study about it.
