there are a lot of people being introduced to bitcoin at the moment who don't have much choice but to buy now - there's no signs of bitcoins dramatically dropping in value.

That is not a very good sign, it could mean we are going back to 20, or we could just level off around 200, or it could keep going up to 5000 and drop back down to 2000. Where does your sign say it will end up?
