that's actually also what i have in mind for the upcoming block halving. i will sell 1 or 2 days before the block halving as i believe in these days the highest point will be reached. once the block halving has taken place i expect huge dumps to tank the price down heavily. i will surely buy back at much lower price levels.
But of course it will be hard to earn some money with Bitcoin because it takes a long time to have a higher value.
The $440 price for the bitcoin is low at the moment. We might not see that price in a few months.
