Well, this quote says "regardless of the price of the security", this is part of the sentence I do not agree with
For me, dollar cost average is buying, maybe same amount of bitcoin(for example) at a different price ranges while the market price is going down or in a bear mode.
What is your best strategy for Dollar Cost Averaging, do you do it weekly, monthly?
What do you advice and why?
And my advice and why, dollar cost average is a good strategy to make more profit on your investment since it's helps to bring down or reduce your average buying price, by buying same amount of bitcoin at a cheaper price, you are reducing the over all buying price of all the bitcoins bought in the period.
