Want to not be restricted by a gift card until you are ready to actually purchase something from the company you go tthe gift card from? A Steam giftcard is useless if your not on PC (for the most part) and an X-Box/PS giftcard are not valid outside of the country it was purchased. If you don't want to get screwed like this, invest in GamerBucks. GamerBucks can easily be converted to BTC for gift card purchases on https://coingate.com/gift-cards and eventually will have a marketplace set up for people to sell their unused value from their giftcards. Being a cryto, it never expires, is immune to hacking and inflations, and is an overall good investment in general. So stop saying "I promise I will buy from you" with the purchase of a gift card and invest, instead, in GamerBucks until you are ready to make your product purchase (whether it be a game on Steam or V-Bucks for Fortnite). That way you get what you want when you want it and don't have to follow special rules.
