15Million Lisk first year for DPOS is just too too much in my book, it going to be massive dump to the market. I would wait 2 or 3 years before holding Lisk long.
Overall much less inflation than Ethereum:

Lisk is Lisk and Etherieum is Ethereum. You don't want to be in Eth shadow or compete with it all the times. Still, 15millions Lisk giving to 100 people/delegates first year is just too much.
