Yah I agree with Alexos, maybe crypto is playing differently.

I've definitely 4-bet/been getting it in a ton with 99/TT type hands if someone is 3-betting me a lot. If you don't widen your 4-betvalue/5-bet calling range, then they can just 5-bet bluff you to hell and once in a while you'll call with your premiums.

And I've definitely had many ppl lately 4-bet/call my 5-bet shove with hands like 88 or AQ or worse even.

Personally, I'd rather 4-bet/call off a hand like 99 than play to their 3-bet OOP. It could just be a preference thing.
