In my opinion, real problems are many in the crypto world. One of those are the people itself scamming people like those scam ICO's that are in the market promising the people with good return of investment but in reality, it's undervalued and most of the thing happened is that such ICO has never been successful leaving the investors out of thin air. Another real problem I see is that people who had invested in btc has this reaction to get panic and the fear of losing their investment could result them to do panic selling. These people are only after for the quick money and do not have the patience like most of the old timers and successful investors.
