Thanks @codemojo !
For now bitcoin is the most capitalized and is also the tool that is worth more on all, I think that this year will range between 10,000 and 20,000 (with maybe beautiful roller coaster), say it died I do not know, I do not see it realistic , also because I know that Japan has already adopted it as a legal payment method.
I think, however, that I will be replaced, over time, by better designed and more efficient in terms of speed, but maybe the technology will change and not the name bitcoin (I think it is still the most well-known and therefore also one of the candidates to stay on the scene).
For ethereum, well know that some major American banks have invested a lot in research so could come out some parallel product that works with the ethereum algorithms but with proprietary code, also I live near the Swiss and I know that many companies are moving towards the research and development through the tools offered by ethereum.
What I want to say is that here we are not talking about quality of code or functionality and extensibility, we talk about how one technology is adopted compared to another by the greatest possible number of companies, if everyone uses ethereum it is the market that commands and then will continue to remain in vogue ethereum despite some of its competitors have better features.
As for Cardano, I do not know I do not know I have to inform myself about it, certainly it could have a market too, so I'm going to inform myself what it is 🙏🏾😉
I am a Bitcoin Cash supporter and yes, Bitcoin will be worth 1 million in 20 years, but not Bitcoin Core. Ethereum in my opinion will be used for things like CryptoKitties once Cardano becomes usable. Anyway, we have been working on an idea for a coin that would use "Proof of Social Value" instead of expensive Proof of Work. Check out the proposal and tell me what you think:
