Ethereum (ETH) is 205.1× the size of USDD (USDD) by market capitalisation. Their daily returns move barely together (correlation 0.17 across 31 shared trading days). ETH has been the more volatile of the two, at 65% annualised against USDD's 1%.

Relative strength over 90 days: ETH outperformed USDD by 21.8% — measured on the USDD/ETH ratio, so it holds regardless of market direction.
Measured on daily returns rather than on prices. Two assets that both simply trend upward score near 1.0 on raw prices whether or not they move together, so returns are what answer the question people mean by correlation.
