This way is also not fair enough,
I think you are confusing your likes and dislikes with fairness.
it will be pointless to have people bet on the start as well. For example if they bet on lower odds which is possible the highest chance to win but it close on 23th June.
It isn't pointless to bet at the start and get a near 100x time weighting.
Dont you think it is best to wait them until last minutes to bet? The chance wont be drastically change,
The whole point is you have to make that trade-off between getting a high time weight multiplier and having more information to base your bet on. It is simply a choice.
unless there is suddenly a very huge pump and dump? To have 23th or 30th will just be the same, in a week range does not have much different because the gap that you make is far too safe which people will consider to bet on the safest point here.
Bitcoin moved from $6200 to $8200 between the 10th and 14th of May. Sharp movements in Bitcoin price within a week are common and a pullback to below $6000 was still very possible between betting closing on the 23rd and end date of the 31st.
Why dont you make more options to bet instead of the range spare. May be a prediction like in couple of hours or minutes, it is faster and have a better odds
I did make more options. Have a loke a the options on the June bet.
When we put the May bet up Bitcoin price had been quite stable since December last year. I didn't see the bull run coming so soon so we were a little caught out and didn't have sufficient options on the May bet.
