Ethereum is one of the project that'll do very well in the next bull market, this is because other projects build their tokens on Ethereum and its biggest competitor which was Solana has been eliminated. Although Solana is still trading on exchanges but it doesn't have the trust of the community as it did last bull market and now they're been threatened to be a security tokens.
Ethereum is like a safe place to invest just like investing in Bitcoin is, this two coins can always make you profits but their profits mightn't be as big as others altcoins but you won't lose like how other cryptocurency will make you lose if the market was to dump. Ethereum has so many development going on and Ether can now be staked to get more ether and profits too.
Ethereum is now trading at $1,900 which means you would have made $100 profit if you invested in just one Ethereum when the OP made this post last month. The potential of Ethereum is very big because it's the coin with the second highest market capitalization and it means people know the project and will be interested in investing in it because they know it can make them rich.
Unfortunately, the price of Ethereum is too high to buy because the supply owned by Ethereum makes it very difficult to increase the price of Ethereum. Investments with small capital are very small and require a long process. If Ethereum is the best choice for you, I would rather recommend using very large capital immediately to get quite a lot of profit from Ethereum when the price manages to rise.
