As far as I know, Ethereum is a purely decentralized coin, from a price of 4,300 dollars to falling below 2,000 dollars is also very possible or even up to 1,300 dollars Ethereum can happen.
The strategy might be to prepare a lot of Fiat to buy in stages such as 3,000, 2,000, 1,000, 900, 600, to 300 dollars. It depends on whether we are ready or not for our mentality or funds to buy Ethereum in stages.
This is just my opinion, and sometimes personal opinions will differ from others, including choosing top coins like Ethereum.
I am sure with Ethereum because it has many factors such as almost all tokens in the cryptocurrency world using the Ethereum blockchain.
