Papercrypto is a cryptocurrency trading simulation game. When you sign up, we give you a play money account with $20,000 you can use to buy and sell any of the top 100 cryptocurrencies (100% simulation and not real).
This account and play money are yours indefinitely, which you can use to examine and buy any of the listed cryptocurrencies. This allows you to see what it is like to own cryptocurrency in a safe environment, and you can also see the different currencies and research them by name.
