1) Inflation in global curreny or fiat curreny ( ehtereum and bitcoin is best alternative invetment solution )
2) Ethereum is the best Smart contract creation platform holding major DAPP's in market
3) Real world use case
Yes. I think Bitcoin and Ethereum are the most appropriate investments when global economic conditions are deteriorating. If the real investment is in gold. I think this is for the sake of protecting our finances. But the fluctuation in crypto prices makes most afraid to invest. I think crypto is not a security issue, but a price issue. If we look at security issues, crypto is number one for now.
