Price charts

Ok just a random question…
Is it me or do the price charts for the 4 major cryptocurrencies that sell on Coinbase all look very identical?
They all rise and fall together… seems kinda suspicious to me… whats behind this??

The prices of the other 3 currencies are very susceptible to what happens to Bitcoin, so they tend to mirror what’s happening with Bitcoin. If you look at the history though, there have been times when they’re different.
