I never thought that you would be playing that slot, I kinda avoid most of the Red Tiger's slot because it kinda has lower volatility compared with Relax's slot. Totally got your point there but yeah it could be there for nothing and so far there is currently no plan to make chips into token yet so that button has no purpose at all. I honestly still has hope that someday we might be able to sell all those chips lol 
Actually, you are right, I prefer playing high volatility slots, dice with less than 1% win chance, and in sports betting I more often than not bet on the underdog, in order to either lose my bet or win with a good multiplier. It's just this particular slot, Rocket Men, I enjoy playing I don't know why. Btw, not all Red Tiger slots have low volatility, check out Mega Pyramid, if you like high volatility slots you may like it.
I dont know that slot but all I can say is that Red Tiger slots are pretty decent and some has higher volatility than the usual but it is not volatile enough if we compare it to some other slots. Its not great like other providers such as Relax which is my favourites and Pragmatic but its good enough for some people but definitely not my taste
Regarding chips, I'll cite @efialtis below, for those who missed it:
So, keep mining those chips, guys, and don't forget lock them for passive income. 
lol there is some discussion regarding this but so far there isnt any timeline for this yet which means chips.gg will be focusing on the development of their site instead of developing token
