Bitminter is a great pool. I didn't know that it has been running for almost over 9 years as i was a miner during 2013 to 2014 and the pools were so few and most of them changed their brand name or shut down.

Results of recent halving started to appear on surface. After this news, i expect many other small mining businesses will follow Bitminter as they can't resist.
I think about small miners who use this pool and what they have as alternatives as they can't even sell their old  mining stuff at a good price.
Let's wait and see what will happen next...

So sad to see them closing down since this will have an effect on bitcoin and also wonder if those mid tier as well those bigs will shutdown provably we will be in worse case scenario since this could lead to slowing down the transaction speed or anything bad impact with bitcoins.

This will be a survival of the fittest on the miners side.

My knowledge of mining is preliminary, but I looked for them, they have been working since 2011, but their current percentage is very small. It makes sense to see them leaving.
Perhaps the company’s philosophy is based on the higher the investment, the higher the return, and the sizes of the shares depend on the investment packages that led to the bankruptcy.
I don’t know, but Binance joining this field will lead to a lot of Mining pools to leave.
