1. don't give the key to anyone, not in a DM, not anywhere. if you get robbed, there's nothing you can do about it.
2. same as no 1
3. also same as no 1
4. sleep on it. if it's been safe on a phone for years, there's no point staying up til 5 am torturing yourself, the chance you'll make some dumb mistake (delete the wrong file etc) is not small
5. backup the file
6. backup the file
7. backup the file
Haha true can't lie, i made maybe 200 notes of the same thing because I wasn't sure is it the same thing. But still will see how i can collect all my "garbage" to clean the chain, it is hell lot, deeper i go thru my drives, more i find, maybe most are wiped out, but have like 2 3 to 4 btc worth in the chains, i need some luck only tho and maybe just maybe i can collect them. Find it amazing how i have spent 4 dollars before years and now they worth thousands.. Pure example that if u even never made a transaction you can end up wealthy. Tbh my narrative changed, had over 20k txid for 2 months, still made some change, but the taxes ate em xd
