Not right now, price is so high.
Definitely today is not a the right time to buy bitcoin if you are thinking to invest 1 bitcoin and you don't have something to hold to.
But if you already have bitcoin that you holds it is a very good thing to invest in a long term investment with that 1 btc.
It is not like that you think bitcoins price is worth 650$ man ? not at all !
Note it in coming days or may be months you will see the price jumping from 600$ to 1500$ or maybe around that. Please buy now before it gets too late for buying.
There is no guarantee the price will go to 1500. A sr. member like you should have no better then giving out this kind of ridiculous advice. If you buy bitcoins for profit, make sure to not go all in and being able to hold your bitcoins for years. Just like the 2013 buyers are still waiting for their profit...
