Net hashrate is just an estimate, it is not ideal and this problem exists for any coin - this is especially pronounced when the network hashrate is changing. Some people think that network hashrate shouldn't be reported altogether as it is not accurate enough. I think that Minerals is one of very few coins where one can observe how network hashrate reported by the wallet differs from the actual one.
Why the difficulty is float? 260 -> 150 -> 250
Is it normal in the case of absence of influence multipool and solo mining?
