There is no situation that is too late or too early. Whenever it is convenient to invest, they should make use of the opportunity to invest because from the time you invest, you will notice that the time has changed. You don't have to wait for the price to drop, unlike the way people have been doing it, because when the opportunity was open years back, people did not really take things seriously, and from what they saw, they did not expect bitcoin to appreciate to this level. And does that have belief from the beginning? This is one of the benefits of investing early, and the price will continue to rise and will only come down to strike a balance.
Well, When it comes to investing timing is really flexible so don't stress yourself too much about it you can always start when you are ready. Investment should done whenever one is convenient as waiting for the dip seems like a waste of time and opportunity. Doesn't really matter when you buy in if you plan to hold for a long time because Bitcoin has the potential to increase in price over time. Over the years we have all seen how it has grown.
Everything being said I just have a little advice for new inventors is to start small and gradually increase as they gain experience and also they need to set out clear investment goals which is to hold for a long term and not deviate from it no matter what happens. The market can be tricky at times but that doesn't calls for panicking.
