Hello all!
I offer my service for parsing chat participants in telegram.
I collect @username of all chat users, in the future this user database can be used for mailing / inviting.
I can also filter participants by active / inactive.
Fixed price - $ 5 per chat. If you make a big order - I've got big discounts for you.
Accept payment in BTC/ETH/LTC/DOGE/XRP
