It has nothings to do with there being many buyers or not. It's a waiting game that can last quite a long time as everyone is waiting for a large player to pull the trigger. And exactly that has happened as we have seen the price increase nicely.

Another things is that people think very lightly on the price remaining at more or less the same levels for a certain time. They directly create threads such as OP and complain about the price being stuck. What these people don't realize is that keeping the price at the same levels for quite some time, requires a good amount of support from people. It's not that nothing is happening when the price doesn't seem to move. The problem is that the majority of the people simply don't understand/see it.
