Well, some might screw you over, but some will pay very good dividends.
Ive been on the selling side and we make 5-7% profit/person for each transaction.
I could screw the sender and get like 1000USD. However, Im making more in a long run, so why would I?
There are liars and cheaters in every communities. You just need to decide yourself.
For the partnership, I dont think any senders would want to find a new guy to help him sell coz youll have to go over the risk/trust process all over again for maybe 1-2% extra profit.
As for reciever(seller), getting new/more partners would means more $$.
I,myself, would love having more partners to send me to sell. But good partners are hard to find.
ps. Ive been working with hodlsquat and its been very successful so far.
if you want proof of successful tx, feel free to ask ^_^
