To #5 you can obviously play around with your settings to find the optimal configuration but what you commented above is basically good. In my experience, you will see that one of two things can happen. Either a coin will sky rocket/drop and you will forget about it and so as the community (which probably just as much as you became ascendant). Or a coin will turn into trash on a bad day which could have been avoided had the user correct their settings earlier on. This of course would generate more losses for optimisers but it’s definitely something to watch out for.
