Will every IoT device will have their own wallet with their own seed, or how is this planned?
What if every IoT device will have their own seed and so we run out of seeds? Is this possible?
What if I accidentally generate a seed that's already used? Or is this chance that 81 characters are the same to small?
Have exchanges like Bitfinex one seed for IOTA and safe their IOTAS their or do they have one seed for every user, who has got IOTAs?
