Pardon me if I got it wrong, but LINE's in-house tokens are not going to be sold on the open market?
That kind of means their internal blockchain serves two purposes reliable accounting and PR (going back to the " blockchain" stock boosting attempts). I suppose the mere mention of blocktech helps in us all in the long run, but this particular chain is not that different from "Microsoft Points" or "Steam Gems" or whatever else freemium currency companies use internally?
