Lol, this is a luxury and full of myths.  It is too difficult to predict these very distant future trends, especially in the world of cryptocurrencies where macroscopic availability is available.  So I think it's best to focus on the trend, enjoy the profits and try to enjoy this beauty. 

ETH will be approximately $ 5-8k as my prediction for this year and $ 10-15k for next year (when ETH 2.0 is welcome)
