I think I can chime in here - Luc is taking the other side because there are a lot of panic sellers in the markets, the 'edge' is that they will overreact and the bulls will buy back to the area that the price cracked from.
You're trading against less experienced traders when you buy from them. The other way round, you have no idea if a base will break and you're trading against the guys who keep buying up coins that drop.
Two very different games.
