As this is not the place to take about it, I just posted the question to get the help for the BEST place to post about it.
Plus, I have a good business where I accept the payments in BTC, so what is the best investment so far ? Shall I withdraw it and save it in a saving account in my bank or what exactly ?
In regards to trying to determine what to do with your BTC I would suggest first browsing the trading discussion board and if you cannot find the answer you are looking for then create a new thread in that board (or if there is an active discussion similar to your situation you may want to contribute to an existing topic).
