How Do You Get a Banker Out of a Tree?

I always plead caution on trading 212 more so. I'm still unclear of the consequences of what happens if these go to school. If you go maybe to an Abi and M-row, a bank, you pay decent fees to it. You'd probably still pay like 10 euro per transaction or something like that. So in the end, with that, therefore, I'm still going for low-cost brokers because they are checked by the regulators who see it's working.
