Edit:Here is a chart.
I have a chart here that will prove that this time is the best to buy bitcoin. It seems like bitcoin price spikes down. This is only for today's chart.

I agree with Y. The best time to buy bitcoin and other cryptocoin is when price down or just low price. I use this pattern and and buy smth when marker downs. And advice for those who buys tokens. The best time is when price is too low (even if it is risky). Because in future you may earn a great profit if ICO is cool. For example, I have invested in ICO EON and I am sure that soon I will get profit because it is good project.
