Earnings should not be promoted when pool is not available anymore.
Recently, matic/near/… where promoted.
For the first one, the 12% earning was not available anymore but at least there was a 4% alternative.
For the other one, no alternative. I invested and had to convert back to another token to be able to stake…
Warning of exhausted pools should appear on buying page (here is what you will/won’t be able to do).
If asset is part of portfolio but pool is not available, it should still appear but greyed (works for matic as there is alternative, but for near nothing appears, while it should)
