I've had a mini cash ISA running for quite some time, but I've been looking at a maxi ISA because it has the potential to make more money. My provider will let me wrap ETFs in an ISA and some of the ones I've been looking to invest in will make 20-40% in a year and have a decent track record over the last couple of years. It seems to me that I can invest all of my ISA allowance in ETFs and watch the sum grow much more rapidly than a 6% cash ISA. If it doesn't grow by the CGT allowance then the money is all mine, minus fees and such. It all seems too easy. What am I missing?
