Not necessarily and the decision to buy now of either the rvx.wt or rvx.wt.a depends on your belief of where the price will go to in the near future (pre 2021 expiry if unused of the rvx.wt)

If you believe that the price of RVX will just plod along without reaching above 2.05 by 2021 but go up after that to $4.00 plus by 2023 then the RVX.WT.A is the better buy.

I believe that the chances are the price will go up above 2.05 by 2021 and thus the RVX.WT is the better buy than the RVX.WT.A

Right now I have been buying the shares themselves since, if as I believe, the share price goes up to more than the 2.05 value by 2020 something then I will make good money on the shares and I already have enough warrants anyway.

I am unenthusiastic about buying or selling warrants at this time
