"******** are getting too mainstream and therefore are no longer a good investment" I feel like this line of thinking doesn't really apply to crypto. That way of thinking is older than crypto. Goldbugs have a outdated way of thinking as well "If you can't hold it in your hands, it's not real" which is obviously false. And since cryptocurrencies are still one of the most unique innovations we've seen in a long time and have a very wide range of use cases, I don't think we are going to hit any major road blocks for quite sometime. That line of thinking may cause a dip in the value, but the crypto market will still recover and continue to grow over time.
