The technology needs time to grow organically through the internet like it was doing via Silk Road and online transactions, not media frenzy driving impulsive and everyman investors over to it creating bubbles and crashes, making people fearful of it.
My biggest problem with crypto is the diluted sea of different currencies when even the original Bitcoin hasn't reached potential as a useful and widespread currency. The irony is that without backing by a centralised banking system, creating tangibility, no society is going to properly adopt any one of them. The moment someone was able to make a meme out of it (dogecoin) is when I grew wary of these factors.
