The niche is really new and unique one, I've never encountered any such projects yet. But in this regard, I doubt that Hamster marketers will be able to keep within the budget and attract a planned number of vendors and buyers to the site. Ill still refrain from investing; maybe later I will purchase coins on a crypto-exchange.
Its your right, but you should be aware that the coins will cost much more than $2 (the current value on the ICO) on the exchange. As for attracting vendors and buyers, marketers have already planned a strategy and calculated all the costs, so there wont be any problems with the promotion of the site.
