Oppies seem to be running at a tighter arbitrage nowadays, finished 2.6c V heads today.
Still value on leveraged quantities, IMO, even w/- 3c conversion deducted at TO (To assumed 20c & 30c)
11k buy @ heads (11c) = 100000 @ 20c = $20,000 - 81% ROI
@ 30c = $30,000 - 172% ROI
@ oppies (8.4c), = 130952 @ 17c = $22,260 - 102% ROI
@ 27c = $35,357 - 221% ROI
But please DYOR .......... and remember, gamble responsibly
