Yes - ideally I wouldn't be writing about such things
TBH I doubt it'd be my posts on earnings that would attract non-desirables - it'd by my big fat wallet page more generally, same for everyone else!
At least with Hive my master password and owner key are in cold storage on an encrypted USB so that's a layer of security!
On the UK tax law there's nothing specific on my return that asks me about crypto - and I don't actually 'earn' in fiat, so I think I'm safe!
RE: My Hive stats for last month: not bad at all!
