Ecosystem tokens, including ROOT, ASTO, SYLO, XRP, VORTEX, XRP:ROOT LP, as well as ETH, USDC, USDT, and DAI receive an RP bonus simply for being held on The Root Network. If you hold those tokens on The Root Network, then you will earn RP proportional to the amount you hold.
However, tokens held on the Ethereum network do not contribute to your RP.
It is important to note that collectibles (NFTs) held on Ethereum still contribute to your Collectible Score and thus your Root Points, as long as your Ethereum wallet is linked to a FuturePass.
