Dobi Exchange is one of the typical example I have run into it in the last few years that has not survived markets up and downs. I think that the crypto space was overwhelmed with crypto exchanges and it is quite good that only the strongest will prevail. I am not sure if there is any upside to have so many exchanges that does not bring any innovations. In case of the Dobi exchange there was not active community on any social media that they had. There was issue with liquidity which is alpha omega to each exchange. In my humble opinion it is more worthy to establish the swap services and route to other liquidity providers - that means huge exchanges. I do not see anyone using exchanges like Dobi in these times. I am still looking for new innovative exchanges and see that there is still room for them.
