We offer free shipping.
So there is no real benefit other that trust to use bitmain.
But you said "free shipping deals are closed"
Sale prices now closed and free shipping deals are closed.
We offer group buy on the forum if members wish that can always be done via escrow.
"Group buy", what does it mean?
Like some people or a person buy ASICs in bulk, such as 10-12 units? Home much the minimum amount for "group buy" ?
People can trust your site as long as escrow involved.
Are those ASICs new (never used before) ? Do you offer any guarantee such as replace it if ASIC is damaged upon receipt at the destination?
