For me, it's really pricy and I can't afford to buy those. I don't want even to buy those fractions as I don't see any sense doing it.

TBC is known for scam because of super expectation that it wil be worth billions in the future. In terms of Primalbase, which recently on sale of 1 token = BTC3, I don't want to risk money here. If others can and they see it will be a good future, then goodluck to them as investors have different views about ICO. And besides, there are lots of ICO today which I put some money on them that's why I don't have much left to joined Primabase ICO so now I ended up waiting for bounty rewards.
