Cost isn’t the issue with recovering wallets with small amounts because the team already said, they would consider recovering wallets with small amount as a favour but I think they charge a 20% for recovery which is fair to me but I think these fee should be paid after the wallet have been recovered and not upfront.
Do you think anybody would pay for wallet recovery service before the fund in the wallet can be recovered? I don't think so and it's only someone that is not sincere will want to get paid upfront before a wallet can be recovered.
I have seen cases of people that looks like scammers asking for upfront before they could work on wallet recovery cases. I believe if fund is inside the wallet, after recovering the fund in the wallet, the percentage agreed rate can be withdrawn after the job is done.
Yes people can be funny at times and ask for an upfront payment for services like this.
Personally, anyone who asks for an upfront payment for a service like this shouldn’t be taken serious and possibly be seen as a scammer because why would someone want to be paid for a job that isn’t certain to be done yet when there is a higher chance of them getting paid.
Scammers are sweet talkers and if you get get caught up in a situation where you are asked to pay upfront for a wallet recovery, please stop every conversation with such a person before you get so sweet talked into doing what you might end up regretting.
