What this has to do with the topic?
BTW.. if you are interested, then you can try gold trading using the stock exchanges. There are two options. The first one is the ETF (Exchange Traded Fund), which is also known as "paper gold". The second option is to trade in gold futures and options (F&O), but I should warn you that it is a very risky option.
Not a fan of ETF's, you are only trading promises not actual metal.
At least with bullionvault you are trading allocated gold and can take delivery of the physical metal if you choose.
We all can use Bitcoin online and that is because it is digital money and it will become also more acceptable.
The feeling of holding gold in your locker is far better then holding bitcoin in your wallet, Gold is precious and will continue its shine in future too.
