The spot circulation volume calculated by the pool is 18.6m. A rough calculation of the current price: 44450/18600000=0.002389784946*145=0.3428324468 USD. This rough calculation aligns with the actual price. Assuming the funds required for doubling is △X=pool sol*(√2 (2 is the multiplier)-1)=44450*0.4142=18411.19*current sol price 135=2485510 USD, it can be doubled, requiring approximately 2.48 million USD.
