I'm also mining Pi. I have been for a few years now. I have almost 4000 of the things. I'm not sure if we will ever get to mainnet and wallets... If we do, I expect a massive sell off and drop in the price before it finds it's price. If it is done well, it could grow. I am not expecting to be rewarded too much for clicking 3 times on my phone once per day for 2 years... but I have been surprised in the crypto world before.
