I don't think there is some real connection between altcoin and Bitcoin market. Yes, trends on both influence each other but on the other hand each of them is functioning independent and I don't think that solving some issues on the altcoin market would necessary influence Bitcoin market in positive way and prevent it from dumping. There are many other factors that cause dumps and corrections.
That kind of connection between altcoin and Bitcoin market that would beat negative influence on both sides isn't achievable.
I think it has connection, trend market are influence by Bitcoin movement. Whether pump/dump on altcoin market can influence on Bitcoin price, i don't think so. But Bitcoin pump/dump affected much on altcoin market. I think to solves this, people need to give knowledge about how doing safe trading by not following trend pump and dump from some groups on social media.
