So you believe this, but you also believe the price of Tulips in the 1600s is directly applicable to bitcoin.

Is it? Damn! And here's me using it as a currency to buy a huge variety of goods and services for years, both in person and online, from around the world. Should I PM you a list of all the vendors I use so you can email them and tell them that bitcoin isn't a currency after all and it doesn't have any value? Maybe if you could also ask them all to send me all the bitcoin I spent with them back to me again. I'm sure they'll all have absolutely no problem with that after you tell them it's worthless.
