As the price goes lower, you will be able to get even more coins for the same amount of money. So I will always at the very least keep buying more with the same amount of capital.. But I always go bigger as I layer.. so if you bought 40s and paticipated in the bounce, maybe selling some 42s .. then I would likely buy 38s with the same amount you bought 40s earlier.. but if it continues lower without a bounce, then I get in bigger, and bigger layering.. Im not sure if that makes sense to you.. So my first buys are usually the same, but im always hoping that it will continue lower without a bounce.. I want a real panic.. so if I get the opportunity to get a second buy or a third, they get bigger and bigger.. but usually I only get the one buy and then a bounce, and I profit but am a little disappointed.
