yeah, Bitcoin was designed to be a digital currency, but the reality is that most folks where I live, and probably other places too, arent really using it to purchase their food or pay bills.  Most folks are just treating it as an investment. Its all about what people see as the most profitable use for it, and for now, thats mostly holding onto it.  Why isnt it used more like regular money? Well, governments are still skeptical of it, and still, barely any stores actually take it and  also, the price can swing wildly making it tough for everyday buys. 

But, to actually answer your question, yes, I have used Bitcoin to make purchases, and I definitely intend to do so again in the future. Do I have any regrets about past purchases? Absolutely not! They seemed like good decisions at the time, and honestly, I never want to look back on them with regret.
