Will there be a possibility to run more than 1 masternode on a wallet?
Technically it's possible, there are other coins with masternodes who do have the function to run as many masternodes as you want on the same wallet as long as you have a unique public IP for each. I hope PieCoin will have this function too.

VPS should be just fine. I'm hoping to run on Windows. For what it's worth, I think PIE coin will be just fine. Let's give the dev an ample amount of time to get this all started. I bought first under 100 sats, then sold like an idiot

and rebought at 150. With active development and a strong community, price is sure to go up.
Now is the waiting period . . . the hardest time to be an investor in crypto. In the meantime, if you support the project . . put up some buy support on an exchange. The BCC crap is over now, and hopefully we can get back to business as usual in the alt world.
