I'd recommend buying a little bit of Bitcoin Cash, Ethereum, and Litecoin. You can buy them on Coinbase (which is easy and safe), or Gemini (which is a little bit more complicated). You can also buy them on Binance or other exchanges, but I don't recommend doing that until you've built up your knowledge base and made sure that you have your security set up correctly.
There are a few ways you can go about buying your first bitcoin. You can either buy it directly from an exchange, or you can try to mine it yourself.
If you're looking for a more direct route, you can purchase bitcoins from exchanges like Coinbase or Gemini. These exchanges allow you to buy and sell bitcoins in exchange for fiat currencies like USD and EUR.
If you're feeling adventurous, you can also try mining bitcoins yourself. This involves using special software to solve complex mathematical problems in order to earn new bitcoins. While this may be a more difficult route, it also comes with the potential for larger profits.
There are a few different ways to buy bitcoin, but the simplest way is to use an online exchange. My personal favorite is Coinbase, which allows you to buy and sell bitcoin, ether (the currency of Ethereum), and Litecoin. You can also use Coinbase to store your coins in a digital wallet.
Another popular exchange is Gemini. Gemini is based in the United States and allows you to buy bitcoin with US dollars. Bitstamp is another option, but it's only available in Europe.
Once you have your bitcoin, you can use it to purchase goods and services online or you can hold onto it as an investment.
