Correct, you could save up for a downpayment by installing solar ASIC systems in existing homes. Set up a profit sharing arrangement. Don't even mention bitcoin, just tell customers you're installing solar that pays a rebate. Start a company and build the future starting with existing solar installations.

man you giving me a idea but i need to see how it works in Aussie homes
Do it. The future ain't gonna build itself. 
these machine will heat up the homes and generate noise as well day and night!!! Also thay gonna ask whats this for. well if you dint tell then govt. might say why you installing and not letting know what this device is. regulation aspect of mining
1. Vent the heat when you don't need it.
2. Many different noise reduction strategies: Mount the ASICs outdoors or in the basement/crawlspace. Use quiet fans. Use immersion or hydro cooling.
3. Solar powered miners don't run at night.
4. Don't break the law.
