I sold out of 4DS some time ago at a significant loss due to the 3rd platform lot having issues and not being convinced that the company had the cash to get through the 4th lot successfully. However today they announced a successful test series and the SP is up over 100% at its peak. Now playing in the same area as Weebit. Now they need to commercialise it. Good luck to those who held.
