For me, it's like gambling investing on Pi Network, because at the moment there is no news which Pi Network will list on which exchanges.
Indeed, these projects could be profitable in the future, like Polkadot, which took 3 years to feel profitable. Everyone is free to choose,
because if you believe in Pi Network projects, please just invest. I stick with my decision that Pi Network is not a good project.
The free Pi network doesn't make sales like an ICO, everyone if you want to join just by downloading the application they don't need to pay so what you say is gambling or investing then you don't understand what Pi network is
