Blockchain is the first time wallet I know in the world of cryptocurrency technology, BlockChain is a wallet where users can store cryptocurrencies safely because it has a very good security because only I can save the key, keep the user's privacy. With wallets in BlockChain users can manage the assets very conveniently and the BlockChain wallet supports high mobility such as on Android and iOS devices or laptops that greatly facilitate us during the trip.
And according to information I can in some developing countries in the world have even implemented a national currency based on Blockchain, such as Bitcoin, and its technology is also used by some major charitable projects to help those who do not have a bank account.
