I do feel you are in the right Ball Park as the number of active users according to me is around 45000 - 70000.
I have not done any analysis but just yesterday I made a post about Why My Steemit Feed is showing less Posts. The reason might be because of these inactive accounts. I follow only 232 People on Steemit but my Feed used to be jam packed with Posts from other people's but now those are a bit scarce.
So I believe that there are a lot of Inactive accounts on Steemit and one reason for that might be because of this Bear Market.
I think this is a very fair comment. Just for the record, the approximately 60,000 I tabled in the blog was a conservative estimate and I feel the actually number is less. Stephen
There are many more reasons for this decline too. I have been thinking about making a post about this.
For example I am from India and since the RBI Crackdown against Cryptos I have seen several Indians just Powering down and taking their Money and getting out of Steemit.
Then again some people think since the market is bearish it would be a waste of Time for them to make a Post on Steemit as they will get less payouts. Instead that is the exact opposite, as when the market is down you can accumulate more Steempower from your Posts.
