If mainstream companies get into crypto, is that good/bad for trading?

If IPOs, earnings calls, or knowing a company’s move can affect their overall stock price in the traditional market, do these things happen to tokens here? Crypto market is super volatile, but I wonder if these things can still affect the way tokens perform or how traders look at their portfolio.

I’ve been reading about mass adoption and saw news that Transient wants to make crypto accessible to most businesses by making it super easy to make smart contracts. If this pans out, this means more traditional businesses will likely make it to the crypto scene. I wonder how this could affect the current market flow, though. Or not at all?

I know financial companies like Visa and Mastercard are already trying to get into crypto, but I wonder what happens if other big industries start getting into crypto as well. Is that a good thing or a bad thing for traders?
