Thought so... So how can you know when you've reached a low point? Is this the lowest point in our history?
You may think it's impossible that bitcoin will ever return to these prices, but people who waited for a dip at 1400 had the same idea, and the price went down a lot and they waited for it to go down even more, and when it started to go back up they waited for it to go back down, but the price only kept going up and never saw those numbers again.
So, purchasing every dip is a fantastic idea, but it's not something you can easily do yourself without knowing when you're at the dip, implementation is more difficult than the advice. On the surface, I agree with the concept, however, I've had several failures with implementation.
