Hey Tungfa, Do you remember how much he charges for that service?
i think it was 20% ?! but i am honestly not sure
i think all details are on his webpage
just to clarify
he can NOT crack your encryption or anything like that,
he will help to recover a 'lost' password
meaning, you give him the passwords you think you used and he will work around that !
My story went like this:
I had my password, but suddenly it did not work anymore when i tried to get my MN set up,
i tried and tried all kind of variations
after 3 days of trying (+ going crazy)
i contacted Dave,
gave him my wallet.dat (with 1000 Dash !!) + the password it should have been
2 days later:
password recovered (there was a spelling mistake in the password)
he send me back my wallet.dat (- 20%)
and all done and happy !
I know of a couple of other guys who used him too
(with serious amounts of BTC)
Edit:
high 5 to KeePass
i use that too, evan on iPhone ! amazing app + he now accepts Dash for donations
(gotta love the germans)
