I won't say Ethereum is a great investment now because the price already grew up high!  The recent price spike was for the Ethereum testnet 2.0 launch date! But when the testnet launches finally, I think Ethereum will show a decline because the hype will be gone. But on the Ethereum 2.0 official launch date, ethereum price may grow up incredibly, even 500-1000$! So, I think this is not the best time for buying Ethereum, rather wait a bit!
