Finding ways to drive money into your crypto empire is a great idea. I would offer a couple of ideas in addition. First find an online place to buy freshly roasted coffee beans. One I like is creeksidecoffeecompany.com. You can try different varieties and have a lot of fun with it. Typically independent roasters offer freshly roasted vs Starbucks where you don't know how long the coffee has been in the bag. Of course you will have to buy a coffee mill/grinder but they are fairly inexpensive. Next, try using a french press (coffee press) to brew the coffee. You taste so much more flavor compared to coffee filtered through paper. Coffee which is freshly ground and brewed this way is remarkably good. Finally, take a look at Gemini.com to exchange USD to Bitcoin. I have had very good experience with them and will never use Coinbase again due to several bad experiences.
