You have noticed correctly, that Ethereum is developing all the time (new projects and updates), as opposed to stuck Bitcoin. People who prefer Bitcoin make their choice in favour of safety, as Bitcoin is one of the safest investments in the crypto world. Those who invest in new defies, new projects and altcoins are ready for risks and they are more likely to have a big profit.
I think ethereum is no less risky than bitcoin. all assets in the crypto market for me have the same risk. it is only because bitcoin dominates trading in the market that more and more people think bitcoin is safer than any other asset.
when we can not manage well, all will end badly. Ethereum is no exception.
