Vaporware has been defined as software or technology that has been announced but is not yet available for purchase, either because it is only a concept or because it is still under design. This definition applies to 90% of all ICOs at this time. It will be months or even years before we find out which projects have proven themselves.
The following projects have been promoted to success. However, for their detractors, they are nothing more than a software looking for a solution. Among them, there is the Tron. This digital motto was one of the greatest successes of 2018. It has climbed into the top 10 crypto-currencies, but not everyone is a fan of Tron, including Monera's creator, Riccardo Spagni. Edge is also among the vaporware.
In addition to these projects, Cardano is also one of them. With a market capitalization of $ 25 billion, Cardano is in the top 5 digital currencies. Finally, Ripple is a fully operational company and one of the oldest players in the sector. Ripple claims to have signed with more than 100 banks, but the problem is that none of them seem to use XRP currencies for money transfer.
