$ETH
Saying whether Ethereum is the best investment is complicated because, in the crypto world, everything is very volatile. But I give my opinion based on the journey I have seen.
Ethereum is like the "brain" of many things in the crypto space, from DeFi (decentralized finance) to NFTs. Its network is the foundation of many projects, and it provides a fundamental value that other cryptos do not have. Additionally, with the improvements that have been made (such as Ethereum 2.0), it is now more efficient.
Of course, there are challenges: fees can be high at times, and there is a lot of competition. But with interest from institutions and the potential approval of Ethereum ETFs (which are like investment funds), many believe that ETH prices could continue to rise. This is not a guarantee, but it has great potential!
The best? It depends on your risk tolerance, but it is definitely one of the most exciting.
