when tokens are traded on the exchange relative to BTC, understandable pricing mechanism. is the flagship and the others were compared. Here, we propose the creation of crosscourse. Prices will be based on courses that are on the exchanges? If so , then not all tokens are liquid and the prices of some are very different in the exchanges, will average?
The network will only work with tokens which are received by smart contracts on everyone, crosscourse to zec, litecoin, Dash will not be used? what will happen to the tokens of other platforms different from etherium?
If I understand you're question correctly, you're asking how the inevitable price differences between smart tokens internal prices & their prices on exchanges.
The answer is the same as the solution to price differences between exchanges: arbitrage bots. When there is profit to be made by a difference in price, these bots automatically come and make trades until they've evened out the prices (and so it is no longer profitable).
To be clear: smart tokens' contracts can buy/sell themselves. No second party needed. That is how every single currency on the network can be fully liquid from day one.
