Each Egg you buy with crypto (other than Bismuth) comes with a 0.1 Bis gift so you will be able to use them.
Each bismuth transaction costs about 0.016 bis, and you will need some transactions to sell or transfer your eggs, as well as make them hatch.
With this pack, you're covered :)
Please note that each egg is unique and built specially for you, with unique transaction data embedded in its DNA.
So it's a customized product that can't be refunded.
By buying, you acknowledge that an egg is a collectible, virtual, non fungible token that has no monetary value by itself.
