As regards security I don't keep anything worth stealing on my phone! :-)

Do you do any of these things:

- run apps
- have email on your phone
- keep contacts on your phone
- calendars
- keep photos or files you don't want other people to see
- connect to wifi networks that aren't your own
- have an airtime contract / substantial PAYG balance

If so you're potentially at risk from having phone out of security support.
It's up to you to make a judgement as to the risks of data being
stolen. But it's simplistic to just say 'I don't use my phone for banking
so I'm OK'.
