To receive, store and send cryptocurrencies you need a wallet.
These purses create "addresses." The "addresses" are similar to the bank account numbers in the traditional world of banks.
That is, just by giving your address to someone can send you cryptocurrencies.
Delivering your address does not entail any risk of theft of funds.
Then we leave a recommended purse for each cryptocurrency that supports Bit2Me. They are not the only ones that exist, but they are the ones we like the most for different reasons besides being open source.
