In the first year it's 15.77%, so the Lisk community has to grow about 16% to maintain the same prices. At a 2M marketcap that's about $877 a day. That's really peanuts, in comparison Ethereum currently creates about $400,000 of new Ether every day. Bitcoin about $1,500,000. And remember, they are mining based. That means people need to sell the Ether/BTC in order to pay for their energy costs.
At Lisk however the LISK don't need to be sold right away. In fact if the community sees that a delegate is always selling all his LISK they will remove the votes from him. Because running a LISK delegate is so cheap ($5 a month), the delegates should pay themselves a part and use the remaining funds for promotion, for the Lisk users, for the faucet and so on.
Also the inflation is not happening over night. Your "45%" are happening over 1825 days! That's a crazy huge number of days for the blockchain space.
** I hope my calculations are all correct. It's getting late here.
But why 16% inflation in the first year? Why not a lower value? What problem does a 16% inflation solve?
Can we vote to change inflation from 16% to 5% ?
I think Devs can still change it before end of ICO.
