Right before it start to go up....
i think the best time to buy bitcoin for those who didn't buy enough back when the price was supper low at $220 and missed the chance is now.
because the price just came back down from $310 to ~$280 so it makes a good point to enter if you have been left behind.
I believe it would be best to wait a little more before going into huge buying sprees, the rest of the US will be waking up in a few more hours and there might be some more selling off that could bring the price ever lower. A lot of people do not yet know that Greece is being given another chance.
I did the same. Bought when prices were low and sold part of it when prices went high and earned a good profit not a huge one but atleast I earned something and now again I am waiting the prices to go down so can buy some more
The only profit that i consider a "profit" is to have at least 5 BTC and more, buying low 0.xx and selling high there is not such profit
