I started out in the US with the same questions and found a convenient solution — the platform https://paybis.com. There you can buy popular cryptocurrencies, including Bitcoin, Ethereum, and stablecoins, without unnecessary bureaucracy. The registration process is simple, support is available in English, and US dollar conversion is fast. I was able to easily purchase my first tokens and send crypto to another wallet without any problems. I recommend first familiarizing yourself with the interface and checking the available payment methods.
