Build cryptocurrency with crypto exchange

Hello, We offer you work your Exchange by 0.5 BTC (or same in ETH), I have been an advisor for a crypto exchange in my country, the best option is to use a cloud service with a serverless and microservices architecture, your server can be easily hacked, for your budget, and thinking that many exchanges spend thousands of dollars only in security, the best option is to use microservices and connect to a headless service in the cloud, you can see how Coinbase works in AWS Cloud Service, is the most secure way to start.

We have 20 years of experience in design and web development, we have developed several web portals and 2 ICOs for tokens, we also work with many exchanges to obtain data on quotes, prices, etc. we are a team of coders with high skills in PHP, JS, Python, C #, Go, and we have used CCXT, the most useful library for connecting crypto exchanges. We have created crypto charts like tradingview to show and analyze cryptos, support and resistance lines, market depth, and others, now we are working on a trading system in .NET and C# for a client on this portal (Freelancer.com), we won the project a few days ago. We chat to define the milestones of the project ...
