All coin mining reduced bigly.
All coins have retreated in price.
The major difference in 2018
was all hash rate was going up.
and all prices were dropping.
Hold on to your hats 🎩 and watch the show.
I am stacking my btc and selling all other coins I mine at a profit.
we should drop under 17 diff maybe under 16 diff.
watching the diff rise again soon will be the key.
soon is sept 2021
if diff keeps retreating well beyond sept 2021 I would get worried.
