At this moment not, because i believe that the price will go down again. The market is very volatile at this moment. We don't got a stable support which makes it hard to count on 600 dollar.
So if the prices goes back to 550 dollar i will buy more agian.
I'm doing exactly the safe thing right now, I just wait on a nice price increase and I hope the bitcoin will rise to a higher amount soon or later.
The bitcoin has a very good worth so that is nice.
