When do you think will be a best time to buy bitcoin and when is the best time to keep bitcoin first before selling?
The price of the best last month is really low and that's the best time to buy bitcoins if you are not buy in last month then you should wait till the bitcoin roll over again into the price of 500 - 600$ before you buy again but for me if you realyl can't wait buy now and then sell it when the price is high again.
Its difficult to believe that price will fall to $500 level again in coming months as we are seating at $700 at a moment and it is expected that price will keep on moving in upward direction in coming months so I think this is still the right time to buy bitcoins as even if price reaches to $800-900 level you can make good profits from it.
