You can google for some studies. Just from casual observation:
1. cryptos have little correlation with broad-based equity movements, interest rates, gold, and most broad 'asset classes'.
2. there are generally strong positive correlations among the cryptos themselves: for example, between BTC/USD vs ETH/USD.
3. there may be some mild positive correlation of ETH/USD with the graphics card makers (AMD, NVDA), as AFAIK you can mine ETH from gpu's.
(and so spill-over correlations between BTC/USD and the card guys because of 2.)
4. there is a lot of talk of BTC/USD correlation with CNY/USD but little convincing evidence. But this could change if bitcoin ever becomes an important method of capital flight from China.
