Hello,
I have an offer for you.
I can build you web application ( Mobile responsive ) + Android and iOS application too, in your budget.
I am a Full Stack developer and have worked with cryptocurrency and various Bitcoin related APIs..
I am sure you would love the quality of work and would provide unlimited revisions until completely satisfied with the final product.
Please feel free to contact me for details..
Regards.
From what I have read , there are only a few more things that needs answering so that I can understand your deployment. So let me elaborate on that . Can you please tell me what type of API you will be using for Data set ( IF ANY ) , Can you tell me the type of Server you have ? and of course what type of CRON it supports?
Once I have these information, I will be able to build more wisely for you.
Thanks and Regards
