No it wouldn't be paypal. On paypal u can have one account and some people may harm you as seller because of "chargeback". Here you can have unlimited addresses, which mean that you can simply receive money on first address and automatically send to second one. You have then backup wallet, as you can always recover money from second to first one if you really lose it.

It's not about chargebacks from sellers, it's about recovering lost. Backup! I just use this word, cuz everybody understand it better.

I wrote about it in the post.
