I totally get where you're coming from - losing money on an investment is no fun at all. Unfortunately, there's no surefire answer to what the "best" crypto to buy is. Cryptocurrency can be super volatile and unpredictable, so it's important to do your own research and make informed decisions. That being said, there are some cryptos that are generally considered to be more stable and less risky than others.
Some examples include Ethereum, Binance Coin, and Cardano. But again, there are no guarantees in the world of crypto! One good strategy to consider is dollar-cost averaging, where you invest a fixed amount of money at regular intervals to smooth out the ups and downs of the market. And of course, make sure you're keeping up with the latest news and trends so you can adjust your strategy as needed. Good luck, and happy investing!
