LBTYA Liberty Global Strange Options Activity

I've noticed some strange options activity recently for LBTYA Liberty Global.

Based on the volume and big block orders, as well as technical analysis, i would buy the $20 strike price Calls with
2023-4-21 expiration date for about
$0.22 premium.
If the options turn out to be profitable Before the earnings release, I would sell at least 50%.

Looking forward to read your opinion about it.
