I suppose thisis an achievement - I think this is a stopping point for me. Until I have a substantial income, then I might push myself to 250 just because the badge is a vast improvement on the 100 badge.
I presume most of you know how to level up efficiently, but I guess I'll give a rundown on how you can do it:
Buy Counter Strike: Global Offensive keys from OPSkins, G2A or another trusted key seller.
Use a "LevelUp Bot", look for ones with a relatively high rate, such as 26:1 and upwards. (25:1 is okay, but 27:1 is ideal. 28:1 is rare but awesome.)
Trade your keys for the cards, pre-warning this can be a bit "janky" and is full of slow loading, I recommendyou do the trade in Chrome instead of Steam's browser, as that was faster for me.
Then you can usethisTamperMonkey or GreaseMonkey script to auto-craft all the cards.
This is the bot I used with a 28:1 rate: Steam Link
I apologise if this tutorial is in the wrong place, I was making a thread about my level and decided to add this in as I didn't think it was worth making another thread.
