It's an interesting idea...

... is putting funds in a GOG online wallet banking? If GOG already has your funds to use (a pre-loaded wallet would mean they have your money), what is the upside for the user other than "convenience?"

But moreso along the sales angle...

... I think it might be interesting if GOG employed some kind of a loyalty / points program. Though that doesn't help with budgeting.

As long as GOG has no access to that money (if you have any proof that they have that access, please provide it), they don't make money (aka: interest) from it.

So, the OP is asking GOG to pay him interest (in whatever form) simply because HE isn't getting interest from his own bank, if he keeps his money in his GOG wallet, instead of in his bank account.

Not that any bank would pay much interest on those few bucks, anyway.

I have no interest in interests.
Claimed all demos and free stuff and been given a number of games,
used gaming account for 4 round years, 48 months paid for about 800 games,
and stopped buying anywhere else.
Op is not gambling, not doing heavy drinking or drugging or flybanging, doing gardening, own family, video games and a cat, and not visiting bank too often, any similarities used now or before except cat can not be confirmed nor denied ^
1-5% back in terms of the above agreement consent ANY form of mechanism aloud to buy the next game cheaper.
I think I will go for 2000 games over time, this is my lifetime PC games library, so You know Gog.com, ...keep it safe or something ; )

I am deeply grateful for all your replies, some funny some scary some dramatic some simply helpful

and.... we got word of DoomSooth "GOG stays up a little longer."

therefore I found nothing better than keep using it as before and You and your answers are the best rewards ^

Although not 100% familiar with GOG's digital wallet process, digital wallets (in general) take currency and tokenize it. In essence, your money goes to the company (in this case GOG) and you receive tokens for it. Those tokens are used within the company's ecosystem (in this case GOG's store), but the actual currency / money / funds used in the tokenization process has been (in most cases) transferred to the company's revenue.

If you look at GOG's digital wallet FAQ, it doesn't mention withdrawing funds / tokens from the wallet, a basic function if GOG was simply holding your money for future use. And in fact from the FAQ it seems to state clearly that funds tokenized are...

"(iv) The GOG Wallet and its funds do not constitute electronic money of any kind and are non-transferable and non-exchangeable under any circumstances. This applies to your GOG Wallet and any funds at all times, including (but not limited to) at any suspension or termination of your account (although if that takes place as a result you not agreeing to any notified change to our policies, then you have the right to appeal to us at our reasonable discretion)."

In this scenario is looks highly likely GOG has all of the money / funds the user adds to the wallet as soon as that money is tokenized. IMO it would be plausible... even probable... that those funds are immediately made revenue and invested.

I'm not arguing GOG's wallet system is bad or shouldn't be used, but am simply looking at how it differs from banking.
