regarding the walk in is possible to do it? Walk in means, come and buy like we normally do in a shop, you walk in, pay cash, or bitcoin and walk out with goods.

I have my reasons to do that:

I want to mine for fun atm, but what if the country I live in in 10 years wakes up and tell me: you bought a miner, you should have earned this, now pay me. Where I live is not unlikely that something like this happens. I do not want to avoid taxes, if it turns out I can make a profit while helping the bitcoin network, then I'll gladly expand to business level, but I just want to avoid possible future problems. Where I live is not like the governments really cares about us citizens, so is a plausible scenario.

Or buy through your shop and then you delete the order, since is not possible not to add an address to the order to complete it, and when someone arrive to collect you give her/him a regular receipt being B2C and goodbye like if I buy a normal piece of hardware.

Is not illegal what I am telling you, but maybe in English I did not explain myself at my best. If you ask your accouter she/he will probably explain the best way to protect your customer privacy.

Btw I just want to be part and help this revolution if I can, I am not here for the profits, I already have a job that is ok with me, this is having fun to me, and I would like it to remain this way.

If is not possible, then I guess I'll look somewhere else, or wait.
