Hahaha...Your advice is so funny to me and it is highly unprofessional, to say the least. Are you telling me that we should buy Bitcoin at both favourable and unfotable prices? That's the way I see it with your advice.
That is the importance of a DCA strategy, whether the conditions of the market are favourable or unfavourable DCA helps you to keep accumulating bitcoin regardless of market performance. DCA helps investors stay focused in their long-term goals acumulating asset (bitcoin) consistently and efficiently despite market conditions.
You see, investment has its own guidelines and principles for effective productivity so we should not due to Bitcoin ignore it. If we did, then it may become an issue over time. Fine, Bitcoin might have reached a very high price in the next 10 years, but how sure are you? This is why we need to be cautious no matter how we are trusting about it.
This question where also asked from the inception of bitcoin 10-12 years ago, there where many who doubted the potential of Bitcoin just as you're asking, and they failed to capitalise on the opportunities bitcoin presented at that time, so many have testified of their regret. When we look at the pace at which bitcoin grew over the period , commanding good amount and competing with so many other assets (e.g real estate, land, gold and silver ....etc) that where in existence many years ago before its birth it shows that bitcoin has the potential and grow for many years to come. It's essential we keep an open mind in bitcoin while accumulating to build a good portfolio rather than ask questions that can bring uncertainties to bitcoin investment.
