Yes, I have played around with Goldex and they seem to be 100% kosher…I did check their About Us and they have some serious guys behind.
In my opinion, they are different to Glint. First, I like the way the app makes me see the prices, market, commissions…I am also a Glint user and I did a quick price comparison last week and Goldex gave me a much better price (the difference is when you sell, really…Goldex was 3 times cheaper) which is not going to break the bank for my £200 trade but definitely big difference.
It looks like they act as a price discovery place and they don’t own any gold themselves (which I really like). A nice touch is that they have this cool Smart Buy button that scans markets to get the best price when you buy or sell. I will wait to get their card and then I can comment more but so far I like it.
