$10 price will give cardano a huge marketcap, so it would be difficult. Maybe if someday the total cryptocurrency marketcap is in billions, cardano will get that price. It wouldn't be very soon, but if you ask me it's possible somewhere in 5 years time.
it can certainly be suitable for the long term, which makes it a definite holder. Cardano currently holds the 8th position on the global coin rating list while maintaining the top currency even though it is now worth slightly above 0.19 $ per single coin. However, if you look at the ADA graph over the course of its useful life, you will see that the ADA has no radical ups and downs in the market unlike most of its peers.
