You choose the right strategy, but I'm afraid you might be wrong when it comes to timing to sell. I agree that November will be a month of declines, but I cannot agree that December will surely be a month of increases. In my opinion, it is very possible that in December prices will still be very low and that the increases will not start until next year.
What you say may be true, but what I see in the market is the opposite where the market has started to look a little bit recovering with some price increases on each Altcoin as well as on the good ones, so is this just for the next deeper decline?
