BTFD and HODL never hurt anyone! Don't worry so much about the quick movements and look for the bigger picture. A good strategy is to buy downward incrementally. Say buy 0.1 at $1000 another 0.2 at $950 another 0.4 at $900 and then you could either buy some at market price or open even lower orders. This will help you catch the falling knife and profit on the rally!
