Minimal withdraw was temporarily increased due to two reasons:

1) Probably you are familiar with the fact that fortunejack.com takes initiative to cover expenses of every outgoing transaction for our players' best comfort. Recent increase of transactions on Blockchain caused withdraw delays and we had to increase transaction fee multiple times to create instant transaction processing infrastructure for our player's satisfaction.
2) We experienced enormous number of fraud abuse cases on low outward transactions recently and limit increase served as a temporary measure to analyse and prevent the happening. Withdraw limit will be updated on Monday at 9:00am server time and fixed on 0.01BTC
