Automated system would be ALWAYS more trusted than any human being.
As i said above, statistics shows that people scam quit for many reasons, system cannot scam quit.
Not sure why different people repeat same questions which were already answered
How we can know that these users are your partners and you're providing to them miners?
I mean you're a newbie without a website, without alibaba, just a telegram account... I am not accusing you but for sure it's a bit strange that a big suppliers has nothing then a ... telegram account ...
BTW the choice of escrow is a critical aspect, that's why people are asking several times.... and until now what you have always repeated is that "you will only rely on ALIBABA automatic system".
Ok I understand that "human beings" can make mistakes. You can explain an issue to human... and of course if they make a mistake they lose trust, it's their main interest avoid any issue .... and for sure escrows (reputable/bigger ones here on forum) doesn't need to SCAM ANYONE
An automatic system can be very well defrauded (example how does the automatic system check that they have sent to the correct address a WORKING miner? ehehehhe

)
I think you need to evaluate the chance to have also 1/2 of escrows from forum.
People will be assured to made this kind of transactions.
You asking me how you should ask Alibaba seller anything ? They have WhatsApp numbers

Feel free to contact them and ask for YCT Matt

Also, i am not aware why that is so important consider the buyer will use shop from Alibaba with thousands of feedback and escrow system?
You saying automatic system can be very well defrauded ? Then defraud it and get paid for your knowledge so they can make it better, that's what big company doing for people who can defraud their security systems.
If you are such a genius who can defraud Alibaba escrow service, i admire you and i believe you should be paid for that knowledge.
