You will make propably more of a higher percentage buying more Waves than buying three Ethereum. Waves is more likely to triple or even 10X, where as ETH might only double at best this year. Just in my opinion. If you're looking for a short to medium term cash out I would suggest waves. ETH is solid though and unlikely to lose its hold as one of the top 5 coins. Waves is good long term hodl too as it will not only rise in price but also pays something similar to a dividend for holding.
