I think you traded away greed for less risk.

If the WT makes money, WT.A will too. The opposite is false. WT could expire and RVX could be bought later in 2021-22-23. 

Personally, I sold WT.A when they were higher than WT to buy WT cheaper. In my investment view, RVX makes a very valuable move (buyout, partner, 2nd BTD, NDA) in the next 16 months.

Edit: GAC, we're saying the same thing.
