Hey, I hope you saw my above price about how the market works. So to give you a little more info: 1) Yes, there are big players (aka "whales"), and the rest of the "small fish", all playing in the same pond. The interesting thing about cryptos is that the are more "money-like" than "stock-like" when it comes to trading. Meaning just like money, where I can buy a fraction of a $, I can also buy a fraction of a bitcoin. So there are a lot of smaller players who will buy, say .01 BTC for $150 right now. But while there is a general consensus that bitcoin is $15k by virtue of people paying that much for it, the "whales" (people with a lot of money or coins), can cause issues because they can put a lot of volume on or take a lot of volume off the order book at once. This happened to Ether this year, dumping the price for a few minutes from >$300 down to about 10 cents for a few minutes! https://blog.gdax.com/eth-usd-trading-update-5d8142b5bdc1 https://blog.gdax.com/eth-usd-trading-update-5d8142b5bdc1 In fact, there is some speculation that a lot of the rise right now is from Wall St. / big firms buying up a lot of coin, as futures trading on Bitcoin is coming in the coming weeks! (But I don't know enough to comment on that theory) As far as preventing exchanges themselves from colluding... it would be difficult but not impossible, because again the price on the exchanges comes from the traders, not the exchanges themselves. (Theoretically it is possible that an exchange could do a bunch of "wash trading" / make up a bunch of fake trade volume to make demand look higher than it was, but given that there are a number of exchanges in a number of different countries, coordination there might be difficult)
