Well, we've just hit a new ATH, and it is totally reasonable to doubt whether it is a good moment to invest. The short answer is that nobody knows what will happen tomorrow or in 10 years with the price, so it doesn't maje much sense to ask whether this is the right time to invest or not.

If you think that Bitcoin has great potential and that a great future still awaits, then it is always a good time to invest. Many people before you invested after new ATHs and, if they didn't sell, they will be in profit today (we can now affirm that no investor lost money if they hodled until today).
