I support the idea for making the cancellation fee cheaper, however in issue#393 the fee is still too expensive for basic member (even more expensive than before?) .
in my idea, we need not to force each user to become lifetime member, basic member should have acceptable fee, and if they become a big user, lifetime member will be better choice.
let me reason what a fee for filled order for basic member is acceptable.
comparing to central exchange, suppose the fee rate for filled order is 0.2%.
suppose the expected volume for 1 order is 20000 BTS(from my intuition), then the fee is 40 BTS.
for basic member, the fee for unfulfilled order should also be much cheaper than filled order.
also considered that a partially filled order is charged as a totally filled order, here is my suggestion for the fee setting under this framework:
Filled order
- Lifetime members: $0.02(5 BTS)
- Annual member: $0.06(15 BTS)
- Basic member: $0.12 (30 BTS)
Unfulfilled order
- Lifetime member: $0.0004 (0.1 BTS)
- Annual member: $0.008 (2 BTS)
- Basic member: $0.02 (5 BTS)
