Yeah, keep buying and buying more. I've considering to set 0.5 BTC buy order in Huobi, for every $20 downside all the way to $200. This might be the one last chance to get coins like this bargain sale.
That might be a good way to lessen the losses. But why not just buy that amount once the price is the lowest?
Because it is not possible to know with any level of certainty when the price is the "lowest". He is describing a way to buy additional amounts of bitcoin while the price is falling. If you were hoping to buy a bunch of bitcoin when the price is eactly $200, then the price bottoms out at $200.50 and then skyrockets you will have purchased no bitcoin however if you bought small amounts over time as the price declined then you would have purchased some bitcoin
