the first one was actually $800+ before falling down to nothing ($0.001)!
and here is the mysterious "how":
move your mouse to the highest price and check out the "volume". it was $40 which was also coming from 3 markets in total. that is how the price started from this high a price.
when a coin is listed on an exchange, in the first moment nobody has anything because the coin was just listed and there was no deposit option. so the owner or maybe the exchange places the first orders. we are talking about a completely empty orderbook. at what price do you place the order? that is your choice. you can place it at $1,000,000 if you wished. now you obviously have bitcoin prior to this on that exchange. you simply buy $40 (a small amount) so that price is recorded in the history books. and there you have it, initial price of $1,000,000 with only $40 volume
