When I say universal I am speaking to crypto's like Bitcoin (that serves a p2p economy), ethereum (that serves a development economy) etc. There are 1000's of alt coins that serve no real original purpose. Monero builds on an anonymous currency. These types of coins I named above serve very real, specific, and ideal purposes for the existence of their specific cryptocurrency. Many other coins I see on alt coin discussions aren't realistically useful per se.
For instance, a crypto that just allows users to buy from multiple online venues using cryptocurrency. There's no real reason why one would need this aspect rather than using their CC on venues like Amazon. Add to that, these same venues may create their own digital currency eventually making these alt coins obselete.
If it's a person that I need to send money to it makes sense to use crypto rather than send a check or cash or visit THEIR specific bank etc since they do not have a CC merchant. Bitcoin makes sense here. Even the anonymous coins like Monero etc, sure the drug dealer angle isn't ethical, but there is an actual market there that anonymous makes sense.
So what I'm looking for is what others feel are very applicable platforms crypto would be a need in current real world needs. What needs can you think of, that were you to see an ICO for that need, would make you see it as a great investment because it has an actual market need that would be filled. Hope that makes sense. Thanks.
Honestly, i think that for most modern countries, adoption still has a long way to go.
The cryptocurrencies with the most usecase are (imo) cryptocurrencies that can be used for anonymous/private transactions, ( Monero etc.) due to them being extremely viable in money laundering schemes/darknet markets. You might not like it, but that's the truth. Why do you think that Putin currently ''supports'' cryptocurrencies? (Evading sanctions?)
Projects like Ethereum are pretty promising (As ethereum could for example be used to make government spending more transparent, etc. ), but to state that they will replace current payment methods/fiat currencies any time soon is just really not the case yet (imo).
And yes, 99% of current ICO's/coin projects are nothing more then a shiny whitepaper. They don't have any real usecase. It's all buzzwords to ride the blockchain hype.
