shubham urolagin If you're building a crpytocurrency trading application you should be using deepstream - you need the extra configuration and you dont want the imposed rate limit and limit on the size of messages with pusher. Deepstream was built by people who were / are traders for trading. Only other option would be to build a different one from the ground up.
I know this because I started building a crypto trading platform a couple years back using deepstream. I understand you don't wish to manage the infrastructure but I strongly advise you reconsider given the purpose.
Happy to chat further / help where I can in messages or discord if you need. Hope your project goes well either way :).
