I still need to get a GCash card at Globe Store. Please correct me if I am wrong 
Yup, You need to have a Globe sim first then dial *143# and choose Gcash it should be at number 8 then register your sim. After registering your sim you can now the go through any Globe outlet that's near you bring a valid id and 150php.
With Globe Gcash you can even put money directly into your bank account. BPI and RCBC only. From Bitcoin or any Crypto that is accepted by Coins.ph then transfer to Gcash then deposit directly to your bank account.
hindi na po kailangan mag register muna sa *143# bago magpunta sa globe store/outlet, pwede na mag direct dun sa globe store para makapag register sa Gcash. ganun po sakin at sa kapatid ko.
