Yes, it is
So what makes it better than any other real world currencies? Nothing really. So everyone runs around crazy waving their hands that USD is dying (it will eventually collapse at some point, or other huge implications will happen), but bitcoin is the same, it can be destroyed by the same problems a real world currency can be, its highly volatile and isn't backed by anything (alas usd is not either).
Besides, you can always hear how the first ppl that started with it very early had some real gains. Sounds pretty much like a pyramid scheme/scam.
And remember people - think for yourself - did the original creators really wanted to "make the world a better place" or "offer an alternative to fiat currencies to help people" or just to make money.
For me - well it might not be 100% scam, but it will probably fail anyway as a bad business project.
