The sentence is "In-game currency can be converted into Ethereum, or used to upgrade the player".

    In general (there are, of course, many exceptions), when a phrase like "in game" is used as an adjective, a hyphen is added. This helps differentiate between the meaning "currency that is used in the game" and " some attribute or activity inside the game currency".

Yes, in this sentence you would need a hyphen for in-game.

This is an example of a compound adjective. Here's the explanation from Grammar Book:

Rule 1. Generally, hyphenate two or more words when they come before a noun they modify and act as a single idea.

Examples: an off-campus apartment, state-of-the-art design

In-game modifies currency, and therefore you should use a hyphen.

    Yes, I just joined mid-September, so this was before I had any idea of that unwritten, self-enforced rule. Oh boy! Look at all those hyphens!
