A totally expected answer from users who don't get this crypto, I think crypto currency is still undervalued by people and they think it as a Ponzi Scheme due to its decentralized system. Also, many users want a guarantee for their money like we have bank mangers when we deposit money in banks and so on but in crypto there is nothing like this, hence people struggle to trust this system and fear getting hacked. But once they totally understand the concept they really love it.
