What you have above is the option to make money without any of the risks. Ask yourself, does any such thing exist in the real world?
Let's see, maybe R13 where the same policy was in place (without the restocking fee even), the miners weren't delivered on time, and we got refunds?
Ask yourself: did you or did you not take a risk with pre ordering? If yes, then don't spam the thread any further.
No, I did not take a risk associated with pre-ordering because I was told that I was able to get a refund up until shipment. I hate pre-orders and have always hated pre-orders. In fact in three years of mining I have only done one pre-order (BFL) which also had a refund policy (I paid in fiat and had the option for a refund in fiat), though I elected to stick with it and eventually got the miner (which I sold at a profit).
If not, then you are being exceedingly unrealistic by expecting someone to take all the risk and you all the profits if it worked out. So, which is it?
It is neither.
There are plenty of risks associated with mining that have nothing to do with pre-ordering.
You can buy miners out of stock (as I have done) and you can order miners with a refund policy (as I have also done) and you are still risking losing money. For example, the miners may break down or just be flaky, difficulty may go up faster than expected, bitcoin prices may crash, you may have pool trouble, network trouble, power outages, etc. Those are risks associated with mining.
The risks associated with pre-ordering without a refund policy (which was not the case here) are separate from that, and not at all inherent in mining. If you want to do that, go right ahead. I don't and I didn't.
