How To Profit From A Killstreak Kit? (Read Desc)

[Frost*]

Hello, I'm very new to trading despite having closr to 600 hours in game. I completed my 2nd MvM tour and acquired an Awper Hand Prof KS Kit with Agonizing Emerald and Flames. Mutliple traders have said that this was a good drop. 

 

Now, my biggest question is how to get the most profit out of this. Should i complete the kit and Sell it? Should I sell it as is? Should I buy a strange to (eventually) use on it? Thanks in advance! 👍
