Unstoppable Wallet is a cryptocurrency wallet app designed to help people who want to buy and hold crypto currencies.

As of now, you can only buy cryptocurrencies with fiat currency and there are only a limited number of cryptocurrencies available. This makes it extremely hard for a newbie to understand what a blockchain is and what cryptocurrency actually is. In fact, it is impossible to even begin to understand how it works unless you have the knowledge and experience. Unstoppable Wallet is here to help you avoid all the unnecessary stuff and focus on the essentials.

It works as an exchange with various cryptocurrencies.
