It is difficult to determine a clear winner considering Cardano vs Ethereum as an investment potential. While Ethereum is much more established and has a much higher price tag, history shows us that it is not immune to sudden price drops. Those looking to invest in Cardano can also get a much larger package - tokens are currently trading for less than three dollars. Ultimately, investment growth is measured as a percentage, and both coins are projected to perform well throughout 2021. In percentage terms, of course, Cardano looks more promising and, psychologically, it is easier to buy it than Ethereum, which costs almost four thousand dollars.
