Yes as long as the money to accumulate Bitcoin is readily available.
Anytime is a right time to accumulate Bitcoin, but I think the best time to buy is when the price is dip and hodl for a longer period of time. And there is not time waiting for the value to drop further before accumulating Bitcoin because no body can predict the Bitcoin market price because it nature is volatile for you might be waiting for the price to dip further while it keeps on increasing in price.
You can accumulate Bitcoin when the money is readily available also with the amount you can afford to loss and for you to have more profit in your Bitcoin investment it depends on the quantity of Bitcoin you were able to accumulate and hodl for long by setting aside your discretionary income which will enable your hodl your Bitcoin for long time.
