Ethereum is the most popular simple blockchain I've ever known.
Solutions for real-world problems such as money transfers and distributed finance have been found based on the Ethereum blockchain.
With an extensive and worldwide network of developers, application development is easy even for those new to the blockchain space.
If Bitcoin is digital Gold, then ETH is what additional financial products might look like in the future. Financial products are not confinement, unlike what the Bank offers today.
With excellent partners, it works very well, which is a fast, cheap and reliable infrastructure tool for future products.
