Best method to accumulate/store

Seeking suggestions after getting burned by Voyager.

Looking for a way to buy and immediately store safely off of an exchange.

Edit: Fairly new to crypto. Was a super casual investor with less than 1k just intrigued by the annual interest Voyager offered. Have learned my lesson and am now interested in some more serious accumulation in a safe manner.

Are there any other ways to earn interest on BTC?

Thanks in advance
