I'm wondering why you are doing this. You say that you are a millionaire who's losing patience with Bitcoin, yet you do this stress test. So I wonder what the background really is.
It needs to be figured out if Bitcoin is ready for mass adoptions.
Results will be very important.
This test only cost 20BTC which is about $5000 per day, not much money for USA or Russia or China government.
They could probably even afford much much stronger "stress test" lasting weeks or months.
I agree about the importance of such a stress test and the potential impact a really big stresstest could have on the network. So if you are speaking for the comany, I fully understand the (potential) motivation. But I'm more interested to know why you, as a person who lost patience in Bitcoin, are doing this.
