Some successful projects are doing this strategies, they airdrop remaining tokens. But let's see what will be the decision of the team. Maybe they can give it as a bonus to all investors who bough huge amount of coins.
It's my first time to know that kind of strategy, mate. Seems good marketing action and turns out successful for velox project.
I also heard about some projects giving unsold tokens to their community. But this days, I think its rare to happen now as most developers are using their unsold tokens to get more sales I guess.
That can't be avoided especially there are a lot of ICOs in the market. Well, some of them are really not doing what they need to do like burning the unsold tokens. This is why we need to be always updated especially a project that we participated.
Updates from the team is very important in the project we joined. Having those unsold tokens which we don't know what's best to do in it simply tells us that let us just wait because the one who will decide what to do are the developers of the said project. Let us just respect their decisions and be thankful for the opportunities they had given.
