if to make ethereum as a long-term investment then this is the right time to buy, soon 2.0 will be present and maybe after that we will never see ethereum prices like now because ethereum will continue to increase but with the note that bitcoin keeps its price
It's not clear at this time about Ethereum 2.0, and it all stops at the prediction, so I believe it is necessary to wait a bit longer to know for sure what is happening in this market. I think Bitcoin is still in a period of decline and can completely collapse at any time, so you need to be more careful because there is always a risk in investing. Also, you can choose to invest some other coins because the crypto market still has a lot of options for you.
