If you choose to invest in Ethereum or any other altcoins, It's important to do your own research. It is true that ETH has had a significant impact on the market and has shown strong growth over the years. Also, it is a leading platform for Dapps and smart contracts.
Remember that the crypto market can be unpredictable.
Saying that it is necessary to invest in new projects that will bring 1000% profit are just words. All these new projects have as their main task to make the team millionaires, at the expense of investors who believed that they could quickly get a big profit. Of course, investing in Ethereum you will not get such a big profit, but we can say for sure that you will not lose your money.
