Hi, I am new to NEM.
As I understood right there is no Inflation. You can harvest by choosing a supernode and get rewards from the transaction fees that the supernode collects by putting transactions in a block.
1. How is the supernode rewarded?
2. If NEM gets more used, do the fees also rise like at BTC?
3. By higher usage the value of the token would also rise. So why should a company use this blockchain, if they have to pay more and more for the usage when NEM gets more popular.
The supernodes are subsidised by a preallocated fund that should last for a few more years.
NEM will soon get a huge capacity upgrade so fees will probably never rise above the standard level. If they do then it's a nice problem to have. If the XEM USD price rises then of course the fee costs more, but developers have already reduced the fee once and can again.
Companies will use a private version of the NEM chain and there won't be any fees. They will occasionally need to use the main chain but only to transact with other companies.
