Guys, do you have any suggestion about how one exchange can gain trust into traders. It will be appreciated!
And do you know any crypto communities for Ethereum, exchanges, blockchain where I can talk more about our decentralized platform

The only suggestion is that let your work, your push and dedication speak for you, it is not really easy to gain the trust of users, especially in a market where we have so many other companies doing the same thing, but you can still make your own way, the market is too big for everyone to make it in their own space.
So if you want to gain my trust, you must first have a very good platform interface, your site must be very users friendly, you should be able to offer me lots of bonuses and discounts on my trade, your site must be highly secured to protect my investment or trade, and finally you should try and have volume on your exchange overtime that will keep your project running.
