The next step to take is to figure out what brings cash for your team. As our CS:GO economy guide mentions, there are two possibilities here: team actions and personal effort.
First of all, when your team wins, you don’t need to bother yourself with personal kill bonuses for different weapons. Eliminate terrorists and defuse the bomb — if you play for CT. Plant the bomb and get rid of those annoying counter-terrorists — if you play for T. Your main focus should be on winning rounds, and that will be the best economic strategy.
