In the world of cryptocurrency, pump-and-dump cycles are nothing new under the sun. Virtually every currency ever created will have its 15 minutes of glory before disappearing into obscurity. Cardano may very well be on this list, as it is going up in value like a rocket without any valid reason. Especially considering that there are close to 30 billion tokens in circulation right now, it is evident this price trend can’t be sustained for more than a few days at best.It’s highly doubtful that people will still be referring to Cardano as a top cryptocurrency in future. The project certainly has some interesting aspects, but there will always be concern about such a sudden and rapid price increase.
No offense but what you're saying imo makes no sense whatsoever. This "rapid price increase" you're referring to with ADA can be applied to most coins in the cryptoworld as well. Look at BTC for instance: Was under $6k in 2017 and then all of a sudden it hit ATH @ $20k? For what? Expensive transfer fees? Slow transactions? etc? Sure it has credibility since it was the first cryptocurrency created but doesn't change the fact that this so called rapid price increase happened to most or if not, all cryptocurrencies.
Just because a coin doesn't have many "products" currently available, doesn't mean it has no value. Cardano's team and their researches, analysis, theories, use cases, documentations, etc speaks for itself.
