Most of the people in bitcointalk are holding their bitcoins and waiting for increase the price. otherwise only 30% people are using their bitcoins in the investment.
That's not true.
The truth is most people are posting here they are holding but in reality they're not.
Why would they do it? Most people here think Bitcoin is underestimated now so why would they sell their coins? I think to sell now is silly if you don't have reasons for that of course. If you need real money right away then selling is not silly.
