I never in the stage yet that I am buying 1BTC, most of the bitcoin I get was came from the result of my trading everyday, and from signature campaign.
Yes like many people here, I also have not looked to buy bitcoins in large amount (but I have studied about its feasibility in my country) as I am having multiple income sources for generating bitcoins on daily basis.
Maybe when I turn a mutual fund manager, I may need to buy bulk amount of bitcoins in one shot. Hence I am keenly watching this topic always.
