Just wondering if its a better idea than my investing elsewhere in the usual isa type of thing.
It depends on what the money’s going to be used for.
The law of small numbers means that relatively small amounts held for a short time are quite likely to have below inflation returns.
However for something like an emergency cash fund that you don’t use, over time it would be a better investment, with the added bonus that it’ll never go down in nominal value. However an instant saver account would do the same, especially if you’re below the tax threshold.
If it’s for long term investment, IME, it would be far better in a stocks and shares ISA.
