Like two years ago I have set up an "experiental" custodial lightning wallet on #LNBits (legend.lnbits.com), funded it with like 200k Sats and accessed it via #Zeus app. Short time after, from one day to another I lost access to it, they just stopped the service. I tried to contact them but nobody replied. Never got the funds back.

Not your keys, not your coins. So I have learned my lesson the very hard way. Total loss of 42k.
