What's the alternative?
Stash it under the mattress so you don't make any gains that can be taxed?
Save it in gold so you can be taxed as capital gains (unless you suffer a capital loss)?
Save in stocks & shares so you can be taxed on your capital gains and dividends? Good luck if you need to fix your boiler in the middle of a down turn.
Bitcoin? That has proven itself to be a rock stable currency and you still won't avoid losing your shirt / capital gains tax.
