I don't think bitcoin will be that high in value for a long time but i think that the bitcoin won't die anytime soon. So i think it is still save for you to invest in bitcoin.
But you should wait for the value to drop first so you will make sure you won't lose money.
It is the bad thing of the people that they always say the wrong thing as you know the value and the price of the bitcoin is increasing and we can have the bright future with the use of the bitcoin. I am very sure in the coming days we will have the bright future of the bitcoin and I am sure with this you will buy a lot of the bitcoins and you will see how fast the bitcoin will become the world wide currency.
