I still think gambling with BFG is very risky but now that mining has become more difficult at $16 a BFG token, and there is a BFG inhouse battle taking place I have been using this strategy. The strategy is fairly safe with the stop loss in place but the main issue is that you can't walk away even while using auto bet.
The idea is that the bets will be done fast with a rapid increase in wager and hopefully the stop on profit will be triggered before the stop on loss. This would mean ending on a large winning bet and then resetting the wager low manually. Quite a lot of effort required but has generally been working good. Of course with a long streak of losses in a row you will lose a lot, so not recommended to do this for long.
