Bitcoin is definately not dead, but it's a long way from stable though.
If you need to ask for investment advice in a forum like this, my advice would be to not spend a penny until you've done your own research and know why you are, or are not investing your money. Never take advice from a forum.
Edit: corrected typo.
Yeah I agree do not go out and invest money into something you do not even know. Do your research and then decide if it will be a good idea if it is good to invest in Bitcoin.
But Bitcoin is good to invest in but do not invest 10k at once.
