You will lose that 1,000 EUR if you ask anyone but yourself what to invest your money in. With that said, coins like DOT, NEAR, TEL, BNB, Matic and XMR will perform really well.
Here's a suggestion from someone who's been seasoned with crypto for the last 7 years:
1. Don't trade. You will lose your money.
2. Do not hold your money in one crypto only.
3. Do not buy cryptos which have a cult built around them, some examples would be: ADA, XRP and the obvious scam known as HEX.
4. When Ethereum Foundation sends ETH to an exchange it's the top.
5. Do not pay for trades, people who sell signals can't trade and make money by charging thousands of newbies a monthly subsription fee.
6. Twitter accounts with a small number of followers post more valuable information than those with a lot of followers. Big accounts larp (lie) a lot.
7. Crypto is a weasel infested environment, be careful who you interact with.
8. "If it sounds too good to be true, it is too good to be true.", an example would be UST and the 20% APY.
Good luck my unknown friend, please do not become my exit liquidity.
