When it comes to bitcoins, some see great growth potential and a wise investment, others see a risky, unregulated monetary system that could explode at any time.
Well this is not that easy to explode, some people think of bitcoin like it will vanish into air but its not like this in reality.
I think bitcoin is a very good investment for a long term if someone have the knowledge about bitcoin they will not think of it that the decentralization is any sort of problem for bitcoin. In fact the decentralization is the strength of bitcoin.
