That is a very good question. I considered myself a specialist when it came to bots profit. Now all previous strategies don't work anymore and all you can do is stay sharp and wait for a 99.99% opportunity and hope nobody else does the same. Kinda risky.

My favourite strategy is now to see the bots as 100% promotional tools and ignore direct potential gains. Bid early and hope that others don't or at least honor the profit barrier and don't make it a loss for everybody.
