for the record, i don't think it ill always go up. i don't think it's valuation works as it should have anymore. but i do think that bitcoin is not like physical stuff. for example i would not want 1000 barrels of oil delivered to my door, but i would always accept a 1000 btc if someone wants to send it to me. there is no cap on what a single person can conveniently hold. it's very special in that sense.
