In the Market Rebellion Crypto community, we require the use of full, correct names for our participants. This should match the name you use on your credit card, for example. It is a requirement for your billing security as well. You can use the less formal, short version of your first name (Example: Jim instead of James). To set your name appropriately, visit the My Account page and edit your Account Details. Display name is required to be set as your first + last name.
