[q]Bulk buying/storage question

I’m pretty new to cs investing and I’m looking to deploy a decent chunk of money into cases and running into the 1k item limit issue. obviously storage units help but the 7 day trade lock means you can’t move newly bought items into them anyway, so you’re still capped at ~1k purchases per week
for people holding large positions what’s the actual standard way people deal with this? multiple steam accounts each with their own CSFloat account buying in parallel? or is there a cleaner solution i’m missing
also for those using multiple accounts on CSFloat, does that cause any issues with the platform or is it a non-issue
