My only concern is the bad part. Did you tell them that there'll be storms? Did you explain that there's a bull run but sometimes a bear run? Because I am sure that you definitely not want them blaming you for any of their loss. Whenever I bring people to crypto or tell them about investments, I also let them know that it can be risky. I hope you did this, if not, you can still tell them while it's early.
You are right. Is important to let them know the risk behind Investing in Cryptocurrency. When I bring people into the Crypto world, and they want to invest. I do explain to them that the price do rise and fall. Also tell them about teach them about been patience. If you don't do this things. You might end up been a bad person to them, when there is drop in price of those coin they Invested in. No doubt, Investing in Cryptocurrency is however profitable.
