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
You cannot really go wrong by investing in ethereum, however at the same time even if a coin is a good investment it does not necessarily means it will give you profits right away, during the last year there was only a few days in which the price of ethereum surpassed 300 dollars for each coin if you are interested on investing in ethereum for the long term then this could be a good opportunity to buy it, however if you are focusing on short term profits then it does not seem like there is much upside for ethereum now and it could be a good idea to wait for the price to go below 200 before investing in it.
