Just wondering when everyone buys bitcoin, weekly, monthly or just on the falls? thinking of setting up something regular to ride out the waves..... 
When I have some spare money, I buy a little amount of bitcoin just to increase the number of coins . So yeah I rarely buy bitcoins cause I can just earn it into some signature campaign.
Me too that is what I am doing when I have a excess or spare money. Because even though I can see that the price of bitcoin is not too high, I can't do anything just to wait for the time when I will going to get and have some spare money. But when I'm having spare money the price is increasing so still I'm able to wait for the price fluctuations.
If you have spare money that you can afford to lose, you can buy some bitcoin. It could be better than gold.
