The problems we see with Bitcoin now are severe and detrimental and not at all aligned with its original goal and purpose. However, these issues were foreseen, hence the fork (Bitcoin Cash). High transaction fees coupled with extreme volatility and a slow transaction time is making sure BTC will not be used for small transactions. If things continue to escalate or stay status quo, BTC's purpose will as predicted be just as a backing coin, like gold once was, but even for that purpose, it needs to be less volatile.
