According to the BM's proposal, we are going to have cheaper cancellation fee and relatively expensive filling order fee.
https://github.com/cryptonomex/graphene/issues/393Summary:
Filled order
- Lifetime members: $0.05 (15 BTS)
- Annual member: $0.125 (35 BTS)
- Basic member: $0.25 (70 BTS)
Unfulfilled order
- Lifetime member: $0.0002 (0.1 BTS)
- Annual member: $0.0755 (20 BTS)
- Basic member: $0.20 (55 BTS)
It's desirable to have negligible amount of fee for non-filled order for lifetime member. But it is too expensive (especially psychologically) to charge over 50 BTS for non-filled order to basic members.
Now, we have 10 BTS fee for both filled/non-filled order. I would suggest to keep the fee at the current level (10 BTS or 9.9 BTS, as many merchants do).
The reasons are as follows
1. Higher fee can drive out common users. They first want to taste our product, but too high fee can barrier them
2. This fee can be additional. Many UIA, such as TRADE.BTC, already have market fee of 0.2% (same level as other exchanges). So we may have more expensive fee system than centralized exchanges.
3. 800% increase can be seen as too arbitrary. We'd rather keep the current fee system until the committee is decentralized. (now 10 of 11 is under control of BM)
