The best time when the price is cheap with the calculation between today and yesterday. If today Bitcoin is traded at a price of $ 59,000, then the best time is when the price of Bitcoin is at the level of $ 57,700.
Are you saying that a new investor without any bitcoin should not buy bitcoin till the price dips to 57k+, that is a wrong way of starting your bitcoin investment because what if the price did not dip to that amount, do you mean that the new investor should've keep on waiting when he has the money to buy right away. This is the problem that some people have, they want Thebes price of bitcoin to come down to their own price before buying.
That's not what I said. In my sentence that you quote, I say the best time comparison to buy Bitcoin. I did not say that Bitcoin investors as you mean by what I said above.
Instead I am very agreed with what Jayjuanee said that the price is not too concerned if you want to invest in bitcoin.
I, who has been with Bitcoin for a year, has found an answer why I don't really care about the price, because Bitcoin for me is not only about the price, but the value is a currency.
