when bitcoin rises, all the altcoins get dumped but they don't get dumped equal amount to bitcoin's rise. for example if bitcoin goes up 10% they do't go down -10% instead they go down something like -8% so that 2% difference shows itself up in their fiat value as a "positive rise" creating the illusion that they were rising.

at the top, change the coin from USD to BTC and you will see what is really going on in the market.


they are not red! they are stable. but because their price comes from a market not a shop, and in a market there is bids and sells at different prices, sometimes the website gets the last price as $0.99 and reports it "red" and sometimes it gets it as 1.00001 and reports it green!
