Cardano (ADA) is a project that has a lot of credibility. Especially with big names like Charles Hoskinson being involved. More importantly they are a refreshing and significant improvement over most other projects. Still a long way to go but the claims of Cardano being "Crypto 3.0" looks to be justified.
Price-wise, however, I feel it has gone up too high, too fast. It has now retraced to a more reasonable level though. When it creates a solid support level, that's the time for those who had missed the boat earlier on to buy.
