U.S. federal prohibition makes it hard to get normal banking services and impossible to ship products across state lines. Big investment banks, large private equity and venture capital funds and major U.S. stock exchanges have all steered clear, making liquidity and credit lines hard to come by."
Despite that fact that there have been several endeavors to address this problem using blockchain/cryptocurrency solutions, successful or not as coins for building investor wealth, the real benefits have not trickled down to the legit players in the industry. Their needs are not yet being met.
The need is for a complete blockchain/cryptocurrency ecosystem that is aimed specifically at legal and completely legitimate, yet under-banked and under-serviced businesses.
