It might never go back to normal withdrawals. The timing of the last events is also not suggesting anything good:
1. Lifetime contracts are reduced to 1 year contract - overnight.
2. After this the Website had more issues than normally and they introduced the Halloween discount; probably to attract new investors/money.
3. First the withdrawals were disabled and now they still have a high threshold.


All of this doesn't suggest that Hashflare is doing great.

Edit: Maybe not directly related to Hashflare but Genesis is now selling BTC Contracts that will only start to go online end of February 2018. They can only do so because there main competitor seems to be out.
