If you have a lot of money then why not to take a risk. Let's face the truth that after bitcoin, ethereum is one good thing to invest with. Since its value now is not yet to high then it's also the right time to grab the opportunity....
IMO bitcoin still the best rather than ETH although Microsoft decide to use ETH but doesn't mean that ETH is better than bitcoin.
About the value , yes it's currently low but it's only the matter of time for ETH to beat BTC's value in the future ( but as always altcoin trading far more riskier than bitcoin trading )
