There is actually a better time I would say. Yes, I agree that it’s best you do invest when you’ve got the money to buy just that fraction that would top your portfolio but even then, having to buy at a low presents the idea of having invested at a better time than buying when Bitcoin price is high.
So you are saying someone should wait till when Bitcoin comes down before he or she can purchase, what if it keeps going high so you will keep waiting for it to come down, Bitcoin will never come down to $5 even if it comes down the imagine will be so small and there is no chance of Bitcoin becoming very low anytime soon, if you keep waiting for it to come down before you can purchase you will always live in regret because when waiting for it to come down and it keeps going up you will always regret not buying earlier.
Perhaps you should re-read what you just read and you would get a better understanding of what is started there. Other than that, you’ll just be pushing me to saying the same thing over again, just rephrased.
Now, there isn’t any speculation that Bitcoin would ever drop to $5. Perhaps you heard that from some place else but, not me most certainly.
Also, Bitcoin can never keep going up. It’s a volatile currency and having price movements to be high some times and low at other times is the way of the market.
Now, while you might buy when you’ve got the funds for it (the DCA strategy), it would be lying to oneself to believe you don’t buy at a better price when you buy from a low, hence the principle of buying low and selling high.
Bitcoin investment is a long time investment and when going into it you should always have it at the back of your mind.
I'm not saying buying Bitcoin when is low is bad I'm only saying when ever you have the money to invest don't wait for it to come down because in the cause of waiting it may be going higher or in the cause of waiting you may use the money to settle emergency issue.
So there's no perfect time to invest in Bitcoin if you are planning on hodling for long term or if you start accumulation journey.
