I'd love to hear from devs if there is any benefit or technological requirement for this indeed very weird implementation.
Absolutely. I don't see why I should care about a coin that can't be used until you buy some on an exchange then use it to buy an account. Banks don't charge to open accounts. If they did no one would use them.
Of the dozen other wallet setups I've used for different coins, this is by far the worst.
At least PASL wallet actually works. Look at ETH or MUSIC wallets, those are way worse, freezing/not replicating or even if they do it takes forever.
On your previous point about mining: setting up a private key for PASL literally takes like 3 clicks and from that point on you just add it to your miner config, point it to fairpool and you get PASL accounts filled with your mined coins.
Let us know if you need any help.
