many people are parnoid. and fear their own family getting acess to keys. so they dont just have 1000 copies of keys dotted around the house just in case..
yet then stupidly think its safer to put funds into a custodian where then the user himself does not even have a key to guarantee he can get out his deposit
i completely understand for 100 years people have trusted custodians(fiat banks) and in decent decades had the trust that their deposits are insured by governments even if custodians went bankrupt..
but the cryptosphere of crypto custodians dont operate the same way and dont have the same regulations or even a insurance policy
this is where education needs to come in
teaching people not the "get rich quick" but "if you invest, secure your investment into YOUR control.. because its YOUR property YOUR responsibility. if you hand it to someone else its no longer yours"
