Yes, it does have a purpose, we spend a lot of time writing about it and giving links. I wish it were read. Anyway, PGO is BTC based and can't be used in the defi ecosystem, that is one reason why we made wPGO, which is stated in the above. So our users can access the defi ecosystem and use it. The other use case is to provide a privacy gateway for our users from defi (wPGO) to privacy (PGO) via a swapping tool/bot.
Oh, rest assured that it is read, hence the confusion. First thing that you might be able to clear: this is a warped token, right? A "copy" that works as a bridge for a token between two chains. In this case, etherchain and blockchain. So why do we need a token sale? Wouldn't people be able to just switch their token through gateway like wETH? Seems easier that way.
Sorry you are confused. It is not a warped token it is a wrapped token. It is not a copy, it is a representation and it is not a bridge between chains. PGO is BTC based and wPGO is ETH based, it is impossible (at this time) to bridge the two chains. We need a crowdsale because we have to supply ETH to the DEX LP and we need $ for other things like marketing, partners, etc. The distribution is located on wPGO website.
