Everyone talks about Bitcoin, Ethereum, Solana, etc. And although there are other coins with higher volatility, with a lot of luck and a 0.01% chance of getting rich, you are investing in them.
But remember that there are also RWA - they are Tokens of real-world assets, they are tangible tokens that allow you to invest in physical assets digitally, such as Gold, real estate, etc. Before, you needed a large capital to invest in those markets, but today technology and its Blockchain make the work easy and with low amounts of money you can have passive income.
