There's an announcement for that. They are not going to just change something on their website without announcing it first. Some people will surely be affected with every update so they announce it before they patch it so people can do what they have to do first. Anyway, let's say that you weren't able to get your money since the withdrawal minimum was increased, you can just deposit your money into your fortunejack account to have a balance of more than 0.1BTC. It's not that hard to deal with if you have the money to do so.

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
