Does anyone know a good place to sell Keys?

most buyers only give $2 for every key I would lose $8 if i would buy 20 keys

You trading Steam Money (virtual money) for real money, of course you will losing money..
Afaik, no one buy keys for more than $2.20. (You should also think about Paypal fee too)

There's BTC bot though, but they not gonna paid with that price..

If you're not in a rush you can try your luck in a indirect way. Find people trading away gifts/humble gift links of highly desirable games that sell easy and fast(e.g. Total War:Warhammer), use your steam wallet to get something they'd agree to trade those for without going over their sell price(unbundled games from their wishlists on a discount), get the gifts/links and sell them to one of the numerous traders for Paypal(Total War can go for $12-13 per link relatively easy).
You might even turn up with not-so-humble profits if you dive in that far :3

Nah buy CSGO skins, make sure they are worth $10+ and sell them on kinguin. Most of the rare skins get sold for a higher price over there so you'll probably break even.

Sorry, i don't know any good place to sell keys.
But i bought some TF2 keys recently easily at $2.05.
I went here.
I don't know if it is open to anybody who wants to sell something or what you need to set up a shop.

Only know one that offers $2.13 now. If you want 100% find friends who want something on Steam and pay you when you buy it as a gift.

Dont buy keys ... its not worth it .... there was a topic about the same matter couple months ago , and people insisted on buying expensive skins ( something like 10-20$ ones) and selling them instead ... since you will lose like 20% of your money if you sell keys as they sell for far less then they are worth on market , while expensive skins do tend to sell for about the same price as on the community market ( sometimes even for more )

I will dig the topic if someone remind me as a reply to that comment :P

Are you aware of the VAC bans that also affects people who gift/trade CS-GO on Steam?

Lootmarket seems like the most reasonable place mentioned here

I cashed out 20k worth of CSGO skins and ''only'' received 15k in real life, so you will always lose money, the best way is if you have people you know in real life to directly sell it to them so you don't pay fees, taxes,...
