Technically there is only one limit one how much you can ask or answer here on musing.io. That limit is basically your bandwidth limit. If you exceed your bandwidth limit on the Steem blockchain, then you won't be able to publish or write more content. You can check your bandwidth on steemd.com by using this link: https://steemd.com/@ammachemist

This is how the bandwidth bar looks like on steemdb:


This means that I have 99.99% of my 2.25 GB bandwidth remaining.

Asking questions and writing answers on musing.io is just like publishing content on Steemit or any other steem dapp. Since musing is built on the Steem blockchain, therefore the same rules apply to it as well.

Note: Text takes a very small amount of space. Therefore a ton of stuff can be written with just a few mega bytes of bandwidth.

I don't think there is maximum of questions to be asked or answers. It depends on the Moderators to deem it fit for reward

There is no limit to how many questions or answers you can post on musing.io

The only thing that could possibly limit you, is your bandwidth on the blockchain. 

As long as you have available bandwidth, you can continue posting on the blockchain at will. 

I hope this answer helps!

Now i am assuming that you want to maximise adding value to the platform and the same time looking for some nice rewards in that case i would suggest sticking  to asking questions that are long tail and rank organically on google , while if you are answering the questions try to bring a unique point ,  a point that genuinely describes your thought at the same time try to back it with some resources or fool proof points if possible.


though my assumptions might be wrong , but i think this platform can really kick of when people start adding value by asking genuine questions and try to be fair while answering.
