@LaserBones + Coinbase
Coinbase has 2 platforms and your single login works for both platforms. These two platforms are Coinbase and Coinbase Pro. Coinbase Pro allows you to trade on their platform while Coinbase allows quick purchases and a simple interface. On Coinbase there is a tab on the homepage called "Earn Rewards" here you can watch 20 minutes worth of 1-3 minutes videos that explain several different Altcoins and exchange you receive $3-$10 worth of that coin. I did this a few weeks back and just the currency I earned from watching the videos has nearly doubled. You can earn $9 of XLM off the bat which is a great coin to invest in at the moment. Also if you purchase $100 of Bitcoin you and I will both receive $10 worth of Bitcoin. I would highly recommend tis exchange as it's safe and has never been hacked and the training videos I they provide are very quick to watch and actually enjoyable.
