yes i'm new but if you want
create new account , i will give you 1$ pack for free
wait some days if anything happens
come here and tell everyone that it's scam
i can't tell you how i'm done it but i can assure you that nothing will happens
is it good idea?
Take note that your supposed customers here already have an account on which we don't know what's their TH level now. Meaning creating a new account and you will fund it with gems just to proved that you are legit is 100% non sense idea. You will hold your customers Gmail account here. The customers doesn't have an assurance that you will made a legit deal. You think a th10 or th11 account will just provide their account to you? Imagined the time and effort they put up here.
Want an effective way to prove you are legit?
Pick a trusted escrow and hand them some money every deal you will made.
TH7 / TH8 = $1,000+
TH 9 = $1,200+
TH 10 = $1,300+
TH 11 = $2,000+
Why the price is like that? That's the current market value of those accounts with an increase to be safe
(+ gmail) (disregarding applied effort and time) so in case of scam, at least there is an assurance that your customer will have something in return although it' still a loss. After a smooth deal, you will received your escrowed money.
Of couse I know you don't like the idea but that is the only way I see that someone will take the risks of buying gems from you.
