Low cost of entry 
While it may seem that the principal advantage of ISAs over gold is their relatively low cost of entry and ease of storage, this isn’t as big a bonus as it seems. With investments like The Pure Gold Company’s Gold Saver, gold can be purchased in amounts suitable for smaller-scale investors.
Flexibility 
In addition, ISAs are overall much less flexible than gold, with some fixed-term and others restricted heavily in how much can be added or removed at any given time. Some even have penalties for liquidation.
