What did you mean by "$100 in cryptocurrency"? Did you mean that the payment will be in Bitcoin? any of the top 10 MarketCap cryptocurrencies, or through unknown/volatile tokens?

How is it going? Who will make the payments? Who will benefit from this data?
Payment will be in any of the top 10 MarketCap cryptocurrencies (The winner will choose himself).
