Do you have a working model? If not how would the users be able to suggest?
What do you mean by BTC Crash site. Do you mean something similar to rocket.run ? Because I love the fun of playing there.
Some suggestions.
1. Active chat between users.
2. Graphical and maybe some unique graphics for added fun.
3. Auto mode with multiple options.
In terms of a working model, base it off of bustabit.com. It is not our website, nor are we affiliated in any way. In terms of how it works & plays, it is identical currently. A heavy revamp of the theme is being worked on also.
Thankfully the first two suggestions you gave are already included with the source code we have. Auto mode with multiple options however is a unique suggestion. Are you referring to a more simplified button-based auto mode perhaps rather than entering text values?
