Speaking of manipulation, let's assume that this WhaleMan using these 10k swaps as manipulation tool and not actually used it for dumping,

Then, based on the swap graphs, my wild assumption that his average rate is around 0.11%
then we can see how much it costs for that whale to keep up with his manipulation game:

10 000*0.0011 = 11 BTC / day = around 3,9 kUSD /day

Just saying. It's not that super costly for him, considering he need to keep it only 1-3 days.
