Maybe they have the computational power to create the addresses with the same few leading characters in real time. Some members create up to 6 characters in just a few minutes/hours depending on the difficulty; if it is 4 and you have a really big power maybe you can create it in seconds or almost instantly. Who knows?
Apart from that, if this page has been around since at least 2018... I am curious about how much Bitcoin and Ethereum has the owner scammed.
Is there some way one can know how much has the owner scammed? I suppose that it is difficult to find out since the addresses are not easy to connect.
Thanks for bringing to light this scam Beparanf.
