What makes you think that new people are here only for profit and not to support great idea which bitcoin is.
Because they bought only after the rally was well under way.
If they believed in Bitcoin they would have bought much earlier. Even if only half of those late buyers are speculators, their holdings must be much more than what shows up in the order books.
Or perhaps they are long time Federal Reserve opponents who only recently found out about BitCoin when it was around $220?
Like me?
Not every new person is a "speculator" though I know there are many.
Don't I WISH I could go back in time and buy BitCoin when it was a penny! Not only for the money, but to get out of Uncle Stupids' Fiat Money System.
