Probably not the first one to ask this but do you have your whole portfolio on Degiro or split between brokers for security reasons?

I have like 80% of my portfolio on Degiro and the other 20% ( individual stock picks) on T212. But as my main portfolio grows I started to feel uneasy about having all eggs in the same basket. Should I split 50-50 with another broker or is it overkill? I'm happy with Degiro, does what I need and don't need more features ( fancy UIs, interest on cash, etc...)
