READ BEFORE APPLYING! IF YOU MESSAGE ME WITHOUT ANSWERING MY QUESTIONS, I WILL IGNORE YOUR OFFER! I honestly cant believe it....... I need someone to build a Bitcoin/Ethereum Exchange for me. Following will be a feature list that describes the MVP. I made sure the MVP is as slim as possible, and as you can see from the feature list so far, there’s nothing extraordinarily complicated here. There are more features in mind, but we can discuss those if we end up working together. Additionally I have prepared a few questions for you. Please keep in mind that this is for the european market, regarding security and such. Additionally I should mention that you don’t need to spend much time on the UI, if any at all, as I will take of this separately in a later stage. The features for the MVP: - A customer can buy Bitcoin, ETH for Euros - A customer can sell Bitcoin, ETH for Euros - In the basic wallet, the customer can send his Bitcoin/ETH to any wallet that he wants. If possible, this wallet should not be able to receive transactions, other than the ones that come directly from the platform. - Payment Methods available: Paypal, Banktransfer, Mastercard, Visa - The customer can take his money out of the platform by Paypal, Banktransfer, Mastercard, Visa - Integrate 2-f-a for this platform. My Questions: 1. What Technology Stack would you use for this? 2. In your proposed solution, is the purchase process directly from (the blockchain), or are you using a 3rd party API? I need to understand how the fees work in your solution! 3. Can you give me a rough estimate of how much money you would need to accomplish this? 5. I am a developer myself, just not familiar with the blockchain part. The Code needs to be in my git repository (currently Gitlab), you will work with branches and I will do a Code-Review for everything that needs to be merged. If you think you can do this, please get in touch with me! I should note that there will be a lot more work done at a later stage, so ideally I'd like someone that is available long term. If possible, provide prior work. I should also note that the Budget is interchangeable, get in touch and we will work it out. If you apply before reading I will know because you haven't answered my questions, and I will 100% NOT work with you.

Hi there! I have read the instructions keenly and understood your specifications for the task. I have verse experience in this field and have adverse experience since it is my area of specialization. I will answer your question. 1. I am going to use Python Django or nodejs for the project. 2. Why I am going to use above techs cause I will use coinbase api for customer to buy or sell they bitcoins and coinbase api provides python and node apis. 3. I think this project costs at least 5000$. 4. Not mentioned about this question in your description. 5. I can work using git. My skills are adequate and I guarantee total satisfaction if I am given that chance. Kindly hire me for a quality task. Thank-you!
