$ETH
Lots of experts think its price will go up over the next few years, maybe quite a bit, but it's also a bit like a rollercoaster, so the price can go up and down a lot.
One big upgrade coming soon is called "Pectra." It's like giving Ethereum a big boost to handle more stuff at once and make things simpler for everyone.
More and more big companies are also starting to use Ethereum, which is a good sign. Plus, people who "stake" their Ethereum (like putting money in a savings account for the network) help keep it secure and can earn a little extra.
There are other "internets for money" out there too, so Ethereum has some competition. But overall, most people are excited about where Ethereum is headed because it's trying to make the future of online stuff more open and less controlled by big corporations. Just remember it can be a bumpy ride!
