Expecting 300% increase in growth

Compare to the previous generations, Gen Z do have multiple advantages such as faster Internet access (5G network), bigger social media ( $Facebook(FB.US)$ , $Twitter (Delisted)(TWTR.US)$ ), smarter mobile devices ( $Apple(AAPL.US)$ ) and more online trading platforms and brokerage ( $Futu Holdings Ltd(FUTU.US)$ MooMoo ), allowing them to trade not just stocks, but also forex, options, futures, CFD, cryptocurrencies and many more. Also, some of them are rich and have started their own business. Thus, there is no doubt to the 90% increase, even though I was expecting a 300% increase.
