You are playing with really BIG increments, Ibian, which is definitely fair enough.
As long as bitcoin prices continue to go up (which I expect that they are going to keep on going up, once we get through this rough period.. hahahahaha), I might evolve into much BIGGER increments, but I have gotten so used to my system, that I am NOT too likely to evolve my increments to such a GREAT level as to play "doubling" increments..
Doubling seems to be too hands off for my anticipated ongoing interest levels in bitcoin and/or possibly other crypto in the future, but surely, considering doubling is not out of the question regarding a possible future status (of not trading so much). Accordingly, I can imagine that it can be kind of nice to not be chasing orders.
