To some reasonable extent, the attention coming recently to the crypto space is targeted or seen to be towards Bitcoin, this is another proof that Bitcoin can not be replaced, but will keep getting stronger, while top altcoins will be growing and on their own.
And I don't think we should expect institutional investors to somehow begin to invest in altcoins anytime soon, institutional investors are simply too powerful and bitcoin is the only coin so far that can absorb the volume of their investments, even a coin like ethereum which has a massive market cap is many times smaller than bitcoin just on that metric but when we consider how many people are actually using bitcoin or ethereum to buy stuff over the Internet bitcoin has a massive advantage while ethereum is mostly used to speculate with other altcoins.
