The market of crypto currency is very unpredictable, it cannot be directly said which currency will be the most dominant. It require a lot of knowledge and experienc3e on the market to conclude about the future of a coin. The investors should not completely rely on the opinion of other investor but rather do research of their own.
What we seen until now? Prices are unstable and unpredictable, but interest in this technology is rising. More people then ever, higher adoption rate, countries started to recognize crypto as better system and they working on legalization and regulations of crypto. Nobody can be 100% sure which crypto will be most dominant in the future, but there will be a need for many of them.
Future is bright for crypto, that can be seen trough price. In couple years prices are much higher as people interest is growing, as some people announced and I just quote them, what will happen when companies start to adopt it and different institutions, price will have new train to up and next time it will be wildest ride ever for all of us here.
