I am big time follower of ethereum from initial days i was holding ethereum even the price less than 100$ and also i was holding ethereum at the price of 1500$ . But based on recent development i am highly speculative ethereum price after 2.0 release . Once POS introduced the problem of scalability will be solved Maximum supply will be fixed . So i am slowly investing on ethereum from my savings part by part reasons are below
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.
