I’ve been using the pin# 2FA on there for now because of the the G Authenticator issues I’ve heard about.
I also put in a request for the Blockfolio app to add TradeSatoshi exchange to their roster so that Safex can be tracked again as well as other tokens at TradeSatoshi. They responded and said that they would consider it with more volume or more requests for it.
My advice is that everyone here who uses Blockfolio or similar apps should consider contacting their support to request TradeSatoshi exchange to be added. The addition of it to everyone’s phones will help I’m sure.
