If you mean it would be dangerous in that it can improve itself beyond our ability to understand, contain, or mitigate it, then possibly.
If you're scared of it copying itself and then having multiple existing copies at once, then not necessarily. In that case it would be competing with itself for computing power and bandwidth. Look what happened when bitcoin forked - it lost a bunch of silicon time.
(Cue conspiracies about Bitcoin actually being a hugely powerful general AI disguising itself as cryptocurrency...)
