I don't agree with OP, as he is trying to time the market.

The best proven method to make profits with bitcoin is just to buy and hold. Everyone who has bought bitcoin and held it is in profit. On the other hand, many of those who played at doing what the OP says have lost money and regret it. I have seen it said many times, I shouldn't have traded with my holdings. That doesn't mean you can't ever sell, though.
