If I were younger and more energetic, I’d be tempted to go into competition with Bitcoin. I would market Sphinx Karma Credits, which are as securely backed as Bitcoin.
I promise to be honest and reliable and to hide all transactions from the government, so my guarantees are as solid as Bitcoin’s. Double pinky promise. Cross my heart and hope to die.
Now all I have to do is get enough willing “investors” to buy in. I still can’t figure out how Bitcoin managed that.
Blockchain the transaction record is immutable and sure can be shielded but certainly not efficiently. There is no getting around the money flows are in the block chain to be pulled out and figured out unless your willing to slow transaction rate to where cash is more efficient.
Feeding a small scale money launder 1,000,000 dollars in twenties is the way to find their banks, the fronts, their lawyers, their cleaning people, who sells the boxes to keep all the cash in, their cook and their associates.
