Is it safe to have VPN on all the time?

I've been wondering lately, is it really SAFE to keep my VPN on all the time? I understand the benefits of added privacy and security online, but are there any potential drawbacks or risks I should be aware of? For instance, could it slow down my internet connection or put me at risk for other types of cyber threats? As someone who frequently deals with sensitive financial information and cryptocurrency transactions, I want to make sure I'm taking the necessary precautions to protect my data. So, can you shed some light on the safety of keeping a VPN active constantly?
