The cryptopia had faced complaints and attacks due the community members not be able to check their wallet and not follow the rules, mercatox has a big issue related to deposits and withdraws, soo a new exchange should be the solution, this coin wont go to die, it its just improving and several new features are coming, an api to be used into others projected XRB related should be a good solution, since its a brand new code and without it isnt easy to set up projects.
Is there any instruction on How-to-do? Nope!
The op is shity short.
Not all peoples here are developers, most of they are normal users.
I didnt get your question im talking about download a wallet and let it sync, what you need to do is just wait, im not talking about pools here, anyway im sure sooner or later someone will make some videos to help others that are coming into this project to let them to understand how a wallet works at the moment.
About the api looks like the bomber, owner of bitgrail exchange that will come live soon, will release it soo soon anybody can build their projects with an easy integration at their projects.
