I've been watching charts for the past couple of hours and BTC price reached ATH but ETH price doesn't even moved. Suddenly BTC price dropped and ETH price dropped as well. Why doesn't go up with the price increase of BTC?
As I expected, if you want to exchange crypto to crypto, BTC <-> ETH, if the price of BTC goes down, the price of ETH goes up and if the BTC goes up, the ETH goes down. But why the fiat to crypto value doesn't goes change as well?
1. Bitcoin is correlated to all other cryptocurrencies. And this correlation is positive to a very small extent, but mostly negative. It means when bitcoin price increases, price of some alts tends to increase as well, but when bitcoin price drops, almost all major alts follow the same pattern.
2. As far as BTC and ETH is concerned, the same above pattern, but this pair is also somewhat inversely correlated, one goes up, other goes down, one goes down, other goes up.
3. Why Fiat to crypto value doesn't go up? Simply because it depends on Fiat/bitcoin to Fiat/ETH trading volume. Crypto/crypto trade, no impact on Fiat.
