Coinbase is a popular cryptocurrency exchange that brokers Bitcoin, Litecoin, Ethereum, and Bitcoin Cash. According to their website:
Coinbase is a secure online platform for buying, selling, transferring, and storing digital currency. Our mission is to create an open financial system for the world and to be the leading global brand for helping people convert digital currency into and out of their local currency.
They allow for people to easily purchase cryptocurrency and sell cryptocurrency. Coinbase also has a nice user interface and is easy to learn. They also provide a lucrative referral program.
Right now, Coinbase offers a referral program that pays both you and the person you refer $10 of bitcoin. The catch is that the person has to purchase at least $100 of cryptocurrency for you to qualify. This means that if you sign up through my referral link and buy $100 of cryptocurrency, we both get $10 of bitcoin. This is a great deal and means that you can essentially get bitcoin 10% off.
If you want to learn more about their referral program, you can read their support article about it. One thing to remember is that the person you refer must verify their account to be eligible for the bonus. The offer also expires after 180 days.
Here is my referral link that you can use to get a free $10:

If you sign up through it and buy $100 of cryptocurrency, we both get $10 of free bitcoin.
If you like using Coinbase, you can download their mobile app here and buy immediately here.
Coinbase currently only has BTC/LTC/ETH/BCH, which is a small portion of existing cryptocurrencies. If you want a different exchange that has more cryptocurrencies, I recommend Kucoin. Kucoin is a small Hong Kong based exchange similar to Binance that pays dividends to its token holders.
