Square’s Cash App, aimed at the young and the hip, will allow investing in share fractions.

The Square Cash App is a mobile payments app that allows people to transfer money between cellphones, pay for retail purchases, and draw cash via credit card, or an ATM.

The Cash App also allows trading in Bitcoin since January 2018.
