Thanks for replies

@mikey 4* s21xp for starters shipping to UK I can arrange logistics if needed . Pm me or whatever you want.

Like Phil I am going to run a few with me at work,then a number with a good host

@phil , how long did you plan your ROI to be do you think ?

How much do you think your hardware will be worth after 12 months ?

How do you go about getting your hardware back from the hosting company when you want to sell them and upgrade etc?

Finally what made you choose the host you said ? Because it's in the us etc? As there are lower kw/h ones right?

well he has mined for years and has been on YouTube a long time more as a miner.

Long term existence has meaning to me.

He was a fresh startup as a host last year. he was will to take from anyone as little as 1 miner.

I had 4 t21 miners sitting idol due to my 4 man partnership dying.
and I had 1 L7 running at high power cost earning very little.

So I had 5 pieces of gear that were worth running. He was willing to take them and not force me to buy overpriced gear from him.

So I sent the 4 t21's to him and the 1 L7 to him. the buying was pretty much just the shipping and $250 to set up.

I was busy most of last year selling 150 gpus and older miners on eBay . I had no time to deal with running a mine. As I was liquidating the older one.

So I grabbed 1 s21xp in Oct-Nov and more slowly.

And got to 4 21xp's and 4 t21's

I then told the guy I will add another s21xp and that that box use it to ship me one of the t21's

Did this four times

so I now have 8 s21xp's and 1 L7

and I funded everything with the gpu and other gear eBay sales.

Still pushing out the remains of the gear on eBay.

most is gone.

I no longer have the labor time running a mine.

the mine was a 200 kilometer run trip 3-5 times a month.

the host is zero trips.

I fully own the gear. power footprint 25kwatts

I four way owned the old mine. power foot print 250kwatts.

Trying to figure out roi is not possible for me. due to eBay sales and dividing among the four of us.

but this is better for me as long as my host remains honest.

8 s21xps are worth 8 x 6,000=48,000 maybe 50,000 and 1 L7 is worth 2,500

so the host holds 52,500 of my gear.

it earns 4,200 usd
it burns 2,100 usd a month

so I net 2,100 usd a month

also for now

 altairtech.io = supplier
iowa mining = host

they are only 200 miles apart.

direct drop ship supplier to host.
