Op, from the look of things, we have net yet entered into the bull run which you are anticipating. We are still at the price correction stage which happens after the halving before the bull run starts. So we are likely to see the dump and sideways trend now, and when we finally arrive at the bull run, we'll be experiencing a drastic pump from the price of Bitcoin, though altcoins may also participate in the bull, so if you feel like diversifying you can do that, or if your prefer just hanging on with Bitcoin then that is also the a nice idea. Don't get freaked by the current dump it will be over sooner or later.
