Over at
Bagholders.com, there is a new fantasy crypto trading tool, where you get
$100,000 in virtual currency to trade Bitcoin and hundreds of alt coins.
You're competing against other traders to see who's not only the best, but the worst. A league is currently running and ends at the end of this year. Starting next year, there will be leagues run on a monthly basis.
The league runs real-time data on all cryptocurrencies.
