So after looking through your presentation, as well as doing some research on cost of equipment, import taxes, current value of BTC and the fact that the miner in question is not profitable when you include the actual cost of the miner (If you could even find 50 of them available), and the other fact that ASCI depreciate in value over time, and after 1 year your miner will probably cost a good amount in upkeep, I'm going to pass on this idea.

Also, creating a company in the US, but operating it in Argentina is a bad idea, and is on rocky legal ground as well. For such a small profit margin, just a single issue could cause disaster for your entire operation, throwing you into debt. You need to rethink your entire idea before you try to continue. If you have investors, you should just liquidate the assets and return their investment to them.
