what objectives must a crypto project have to be successful?

For me one of the main goal is the mass adoption of the service/platform.. The product has to be "easy to use"..

For You?

What do you think is the main feature for a successful crypto project?

Cane you give me some examples of the project you are following and explain why?

For example I'm following manly two projects:

1) OPCT Opacity Storage (storage Sector) Working product, easy to use.. Soon will be release the mobile App and I think it will be the gate for mass adoption of service..

2) RNB Rentible. Real estate industry A first-mover dApp for mid-to-long term property rentals, where tenants and landlords can send/receive rent payments in different cryptocurrencies Platform release in December. As per Opacity also for Rentible Team the main goal is a mass adoption of the platform
