We have introduced some changes that may require explaination.

1. We have extended session expiry timer from 48h (2 days) to 168h (7 days).
Reason - mining fees are higher than usual and many transactions are delayed. We are testing how it will affect our service usage.

2. We are introducing new chip 8.192 BTC (8192 mBTC) and we are increasing one-confirmation chip dispensing from 10 BTC to 20 BTC.
Reason - there are lots of high deposits that get multiple 4 BTC chips.
Increasing one-confirmation limit means our recommended per-session limit is increasing to "under 20 BTC".

3. We are increasing minimal deposit amount from 0.001 BTC (1 mBTC) to 0.004 BTC (4 mBTC) and blocking withdrawal of 1 and 2 mBTC chips.
This requires longer explaination. Current mining fees are almost 1 mBTC and sweeping smallest chip result in getting almost nothing. This results in situations like this:

This is an example of burning 33 mBTC to receive almost 8 mBTC.

What will happen if somebody deposits 3 mBTC? They will receive chips that can be split/merge/bet/donate but not withdraw. They can be exchanged for voucher to be used with another session.
What will happen if somebody deposits 5 mBTC? They will receive 4 mBTC chip that can be withdrawn and 1 mBTC chip that can be exchanged for voucher.

Hopefully it will lower the wasteful sweep transactions.

4. We are reintroducing commonized chips (0.25, 0.5, 1, 2, 4 and now 8 BTC). We will keep them restocked.
Reason - when we introduced them they did not had a lot of customers and we were getting out of normal chips often. We have had a lot of requests on support to reintroduce them again.
