I personally think all of crypto is a scam but bitcoin, anyone who plays with alt-coins is just trying to get rich quick... You could say the same for bitcoiners, but it I think it's different.
Bitcoin is the only currency that's leaderless, decentralized, belongs to no company or some 30 years-old "CEO", and is contributed to much like the Linux kernel. You could compare it to TCP/IP versus proprietary protocols du jour.
Or just Google "what sets bitcoin apart to other cryptos".
