There’s a recent article posted on the Cannabis Business Executive (CBE) called, “Is BitCoin an Answer to Marijuana’s Banking Needs? No Way, No How.” The opinion-editorial written by the author gave certain reasoning to why the digital currency was unfit for the marijuana industry. However, it seems the journalist also didn’t do his research like so many others before him.
