Is Uphold a good app to store XRP?  I am in the US.  Coinbase will not trade XRP on 01/19/2021.  Does Uphold has the website allow to hold and trade XRP in its website?  I don't feel comfortable to download the app in my phone and carry around.  I am afraid that I lost my phone or some one steals my phone.  I feel more comfortable to trade XRP in the desktop computer at my home.  Thanks.
