There was this Dogecoin challenge: "From $25 to $10000"
Interesting but to high the inflation and to high the marketcap.

Bitgesell ($BGL) is another bitcoin-"clone" which seems quite interesting on the other hand.
Almost same specifications. But you have the halvening every year and a Tx-burn of 90%.

My challenge now:
The coin costs around 0.024cent.
 buy 100BGL  for $2 
Who know

You know its not impossible in this space!
