Just wondering when everyone buys bitcoin, weekly, monthly or just on the falls? thinking of setting up something regular to ride out the waves..... 
I buy Bitcoin when the price is low because the value of the Bitcoin only gets higher so I buy when it is as low as possible. I also need to have the money because these Bitcoin can still be expensive.
The fact is we would never come to know that which is the lowest price of bitcoins and that is bit confusing as price keeps on changing every now and then so its hard to arrive at perfect conclusion.
