When I first started, I was looking for the fastest and easiest way to start investing in cryptocurrency. At that time, and still at the moment, the fastest and easiest way to buy bitcoin (btc), ethereum (eth), and litecoin (ltc), is through Coinbase . 3 Easy Steps : 1. Register 2. Download the Coinbase App (Recently became the #1 Most downloaded App, passing the YouTube App) 3. Add your debit or credit card & start buying! Optional Step: Take a quick picture of your driver's license or passport to increase your weekly buy limit! (Upload instructions on App, took me 30 seconds)
