Make sure you ask your ETF provider if:

1. You will be able to have 24/7 access to your funds without asking permission

2. If they are incapable of close your account if you hold to opinions that might be deemed dangerous tomorrow

3. If anyone owns your keys other than yourself

If you can answer 'no' to any of these questions, then maybe hold off on the ETF and learn how to buy and hold your own bitcoin without the need for a mediator who will inevitably rug you.
