It is definitely not a pyramid scheme. A pyramid scheme is a program which promises investment returns which are only sustainable by capital infusions from new investors. The creators of Bitcoin never promised investment returns, therefore it is not a pyramid scheme. You might argue that it is analogous to a tulip mania, but that's different. If two people agree voluntarily on a price for a tulip bulb or a bitcoin, that is all that matters. If you wish to hold some bitcoin, I suggest that you not get carried away. Perhaps allocate at most 5% of your net worth to it, and whenever that allocation rises to 8% or so, sell enough to bring it back down to 5%. That way if bitcoin drops to zero, you can lose 5% of your net worth and not lose any sleep over it.
