August

Smartest engine in the business ! Why ? It creates the best pair(s) of crypto&fiat to reach the cheapest exchange rate possible, using rates on multiple platforms and taking only the best ones to ensure you get the best price. You can try it and get up to €100 in free BTC : https://join.swissborg.com/r/augustHDUA

Great forecast app Pros: entertaining, educational, potential real token gains (rewarding) Con: would be great to have more tokens than BTC (spoiler: it's gonna happen soon, on another app developed by SwissBorg)
