I'm one of those who believe Bitcoin isn't risky when compared to altcoins. Those who think otherwise haven't deeply studied how Bitcoin works. For me, the only risk there would be making wrong entry or exit predictions while buying it. If we're referring to market dump as the risk Bitcoin can be thrown into or exposed to, then we should know that Bitcoin is like a cat with nine lives. It never dies. It has the ability of rising from its ashes. We've seen it rise from serious dump on several occasions during the bear seasons after each ATHs in the past.
