I'm interested in building a crypto exchange and would love to elaborate with you. The desire is to build a website only (no app needed for now, app will be about 2 months after), website which fit to desktop and mobile, in the style of the Coinbase.com. Instead of trading in Bitcoin and such, trading will be in security tokens (arc 1400).
It is possible to build together only the external platform (without the real connection to blockchain and its token, wallets, etc.), and it is possible to develop the blockchain together as well.
How much the project will cost? And how long will it take?
As well how does the process work? Before starting work, do you perform a system design in order to understand the UX & UI design, type of database, traffic calculations, security, etc.?
I would love to see projects you have done.
