Ethereum will be definetely $1k but you should diversify to at least 3-4 coins. There are such good coins in the market
I agree, don't put everything into one coin even if you think it's a good idea.
The better idea is to have a portfolio of at least 10 coins, when you choose , also look at blockchain activity and transactions and also future updates and projects that can help current ones.
I wish you good luck in your choices.
