At what point would crypto become a non-risky investment?

At this point in time, crypto is still considered a very risky investment. Its generally recommended that you allocate a very small percentage of your investment portfolio towards crypto because of the volatility. Outside of this sub, I feel like everyone is still very skeptical of crypto and compares it to gambling.

What has to happen in order for crypto to lose its negative reputation? More stability, less volatility? IMO the wild bull runs are why so many people get into crypto, the potential to 10x-100x your money is real.

Are the upcoming ETFs supposed to help this situation? If crypto were to become as common as investing in a 401k, would it have to lose everything we love about it?
