Anyone can send funds to the multi signature address (that starts with 3) but in order to release the funds (send from it) then signature from 2 addresses are required. Once the you generate the address Coinbin should give you more details and everything you should to know.
I don't understand how to receive a payment from a multisig address (that starts with 3).
I can generate this with Coinbin
https://coinb.in/#newAddress(which generate and give me 1 BTC address, 1 public key and 1 private key).
and after on
https://coinb.in/#newMultiSig I can have multisig address.
But once buyer send payment to this multisig address, where the funds go? Which wallet own that address?
How can I receive a payment from this?
I can't find any tutorial or guide on Internet to explain this.
Can you help me please?
Thank you very much
Multisignature address is basically associated with more then one private key (unlike addresses that starts with 1) which means both keys are needed to send the funds from that address. If you want a really detailed explanation then I'd recommend reading this article :
