Hi, we will be able to work with you on your project. Before I provide a technical proposal on the possible implementation of the platform I have a few questions: 1) Since you are dealing with User Data on the public blockchain are you comfortable with only using PKI encryption for security? (I do not recommend storing any private data on a public blockchain as it is accessible by everyone.) 2) Can you provide more details on how you want the blockchain to function?

Hello. I've 3 years experience in Blockchain/Cryptocurrency development and got all your requirements. As you know, Blockchain is a distributed ledger so that all nodes have the same ledger for trust. It doesn't require a specific center authority and it reserve trust by using cryptographic. It uses Peer to Peer network and Proof-of-Work makes block added to blockchain after verify. The advantage of Blockchain is Distribution, Independency, and Transparency. I have used Blockchain technology in many projects and gained enough experience and knowledge as well. I am happy to describe my poor idea about your project, here. Please ping me a message if you want further discussion. I am always ready for you. Sincerely.

Hi there, My name is Yasir - I have read initial brief, so what I understood is that you want to develop a crypto currency exchange website allowing users to sell and purchase crypto currencies in exchange of real money. Users will be able to register/login to the site and verify their identities and can place and track their orders with their statuses. Here are my questions: 1- Can you please list how many crypto currencies you would like to include in the exchange? 2- Do you want to integrate any specific API for the exchange purpose? 3- What payment gateway would you like to integrate? You may ignore the bid & once requirements are finalized, I will then give you firm bid. Look forward to hearing from you. Regards, YK LEADconcept
