Over the past several weeks there have been two events, which delivered good results with very little risk: bitcoin hard fork and bitcoin breaking out above 3000 USD.

In the first case, good results were achieved with a strategy that bought bitcoin and at the same time took an opposite, equal in value offsetting position in bitcoin futures or swaps.
As the value of distributed Bitcoin Cash distribution was as much as 10-15% of Bitcoin immediately following the fork, substantial profits could be realized with relatively low risk. The reason for that was that outright bitcoin position "earned" newly created Bitcoin Cash, while the short position in derivatives were not subject to any value being subtracted. Even now, at the moment of writing, Bitcoin Cash is worth about 6-7% of Bitcoin, which is a reasonable estimate of the level of low risk profits that could be achieved from this one event.

In the second case, our software has recorded multiple inefficiencies at the moment of the breakout. Bitcoin in different curencies and in different countries has been moving up at different times. The biggest anomalies have been about 3-5%, this is how much will be earned when the prices normalize.
