Every cryptocurrency is first movers advantage, that's why people rush to jump on ICOs because they can get in first and make quick easy profits.

It has tons of usage as a storage of wealth. But sadly slow transaction speeds because it was the very first cryptocurrency and there was no way Satoshi could have accounted for the huge demand a currency of this scale would need to support all the people that would one day try to adopt it.

That's why the original bitcoin that Satoshi created won't become mainstream adopted, it needs to be significantly altered. And that said, I don't think we need to continue calling it "Bitcoin" if it is something far different than what Satoshi originally created.
