Retiring in 2024 is still an outstanding achievement for a S9, I mean with the crazy last years BTC's difficulty and the low efficiency of the said S9, this was nice for you to be able to still get free sats until now! (or did you do lottery mining in solo? I would have if I had only 1 S9 with free electricty tbh)
You can sell it for some dollars, the same for the PSU if it is still ok...
A s9 is not rare enough to be gift to a mining museum.
Where are you located?
Moncton Canada.
And I would like to point out that I purchased it for $65 off of eBay.
My approximate guess for the amount of money that it has earned is....
49x 65...... So the obsolete s9 made approximately $3,000.. 😁👍
So I'd say it had a good run. And my intent is to put it back on eBay for about what I paid for it.
