I think the problem is the goals people have who are investing. Most people are only in it for the short-term money. People don't even take the time to read what Ardor is about and what a potential big future it has. The devs aren't building it to get a high price, they are building it to make a difference in decentralized ledger technology in the future.
Ardor is completely new and you think other projects will pass Ardor in the coming years. How? Ardor has it's advantage to started a earlier and is further in development. Look at Nxt, the most stable and secure tech there is around. People who are at events and learn about Nxt now are amazed by the features which are working in the core (not by third parties) for many years now. They have been looking the other way.
Businesses and professional organizations want to use a stable and proven tech before they deploy there project upon it. That's why Nxt is so successful in partnerships with banks, governments and companies. You may not see it at the price, but that's because traders are dominating the price of the crypto world and they only look for profits and not for long term future concepts.
If you hold Ardor it can potential give you a big buck on the mid/long-term by forging (mining) multiple blockchains at once and collecting all the fees. This is never been done before. I am looking forward for it and hodling!
