Selling cards on steam [Solved]

The best you can do now is to turn them into gems.

EDIT: Oh well, reading the responses below, I think I stand corrected.

no , unless maybe u trade it to ur friend who does and have him sell and buy games for u

I use Steam Desktop Auth since yesterday, there's still 15 day delay in trading, but it looks like there's no delay for selling have already sold 2 cards for trying
(to skip 15days trading restriction you must use it at least 7 days I think...)

WinAuth or use an android emulator like Bluestacks. You'll still need to use a friend's phone however once to get the code for it.

Get Steam Desktop Authenticator. It's what I've been using for a long time now and it's great. Easy to set up and use.
Alternatives would be WinAuth or downloading android emulator and installing the Steam Authenticator on it.

You have 4 options:
Steam Desktop Authenticator is probably the best and fastest one, allowing you to have one or more accounts for steam authentication if you don't need anything more than market transactions and trading cooldowns removal.
WinAuth is the same exact thing, but also has the possibility to add 2 factor authentications from other sites and games (Battle.net, probably Humble and such).
Bluestacks 2 + Steam application is the longest and most power-hungry option, completely unadvised.
Finally, if you're into card farming, Archi's steam farm is an amazing project made by our fellow Archi (JustArchi), that allows you to idle games to farm the cards from them with multiple accounts and also includes every function of Steam Desktop Authenticator built in. A bit tricky to configure and has no GUI unless you ALSO get this one but very, very helpful.

EDIT: every single option requires and SMS phone, but not necessarily a smartphone. You just need to receive a code via sms and type that in the configs.

I think I got this to work SDA seems to do the trick, thank you all for your advice. Will try this a little more and then add [SOLVED] tag to post

yup working like a charm,thx all

get a usb broadband dongle and do the sms from there.
