Dark wallet BTC is a virtual wallet that works just like a bank account that allows you store up your funds but in form of virtual assets, like your bank account it also allows you send and make payments.
The wallet's name gives me a feeling of doubt about the wallet. The wallet malfunctions coupled with some bugs and in updated security features and user interface features which might end up jeopardizing all your investments since there are no support team that you can easily contact and complain to. The wallet stores just one crypto currency since it surfaced and I haven't seen an improvement on that making the wallet a less appealing option to me and being a hot wallet connected to the internet without proper management from the developers it might be prone to hacks also.
There is no dispute to the fact that the wallet was once one of the best you can ever think about some years back ,but at the moment the wallet is not very recommendable for use for the sake of security and privacy .
