i think its good time to buy more bitcoin because bitcoin rise up its price too much faster day by day and bitcoin will be more stronger and powerful currency in the world than other currency .
The bitcoin price should rise in the next few years when more people start to use it, so it is better to buy now.
the price will rise slowly throughout the years. a lot people may not even notice the growth as they focus too much on peaks and stuff. these people will also be the first to start complaining that the price didn't go up much, while in fact the price has gone up like 50% if you look at the longer term charts. that's however something they don't see.
