2. Add a 1k Satoshi chip also. Sometimes one needs to play lots of small covering bets and it would be very useful to have a 1k satoshi chip.
Nah, imo 0.0001 min chip is low enough. To be reconsidered
when bitcoin crosses $1,000 mark again.
I think it is best to have a 0.001 chip ...
I don't think betting/clicking 0.0005 twice is a problem for anyone. Current structure is OK, chip amount increases by x5 (with exception of 0.0025 -> 0.01, by x4). Adding any additional chips in between would just look too weird and messy.
