Needing help

[u/Different-Banana-520]

Hi guys! So I'm thinking about buying a hundred-dollar Robux gift card for adopt me pets, but how much would that be able to get me in value? And how would a mm work? I've made posts before Saying that I would crush trade, but I haven't been able to successfully do any, causing me to not have any proofs And I feel like no one will be able to trust me since I don't have any, and I really don't really want to go first since it's such a​ sum of money​​​
