Coinbase is a must have cryptocurrency trading application for any person in the United States. Coinbase is the primary way to transfer US Dollars to cryptocurrencies. Some may call this an investment platform or a speculation platform, depending on your opinions on cryptocurrencies. Currently, as of July 11, 2018, there are a total of 4 cryptocurrencies that Coinbase allows you to buy with US Dollars: Bitcoin, Bitcoin Cash, Ethereum and LiteCoin. In the future, you may be able to buy additional cryptocurrencies as the platform diversifies and grows.
Coinbase provides each user with a real-time price point for trading in Bitcoin, Bitcoin Cash, Ethereum, and LiteCoin. You can track the market for each cryptocurrency and make purchases at times where you believe your investment will grow. This is also the primary way for people in the United States to send crypocurrencies to other platforms, such as Binance, to buy even more cryptocurrenices.
Coinbase requires that you authenticate who you are and based on those authentication levels you can buy and sell in larger quantities of cryptocurrencies. Currently there are 3 levels of authentication. The first level requires you to verify your phone number. The second level requires you to verify your personal information. The third level requires you to verify yourself with a photo ID.
I have found Coinbase to be a reliable way to trade in cryptocurrencies. Coinbase does charge a fee for their service. That fee increases if you are using credit cards to buy cryptocurrencies. Based on that increase in fees, I would not recommend using a credit card to buy cryptocurrencies and would stick to purchase transfers from your bank account. I have had no problem buying, selling, and transfering money to and from my bank account using Coinbase and believe Coinbase is a great way for new cryptocurrency buyers to invest in this new market.
