It is like this, if you can get more BFG if you bet it, in my case I have made many bets playing Coinflip, but you have to be careful, a long time ago I had a quite considerable loss around 1600BFG (BTC) which did affect the account of the merger of the BFG tokens. Here I play coinflip because it is one of my favorite games, however if you already have your BFG it is better to make bets with BTC and ETH so they give micro gains, the important thing is that you add so that the staking is increasing every day and your income liabilities increase. ( It should be noted that it is my personal recommendation, some do not risk their Satoshis at the moment and it is understandable, it is my way of playing to get more tokens.)
Which game you play shouldn't really matter because playing the game you like to play matters a lot more. However you should be careful about trying to mine tokens by wagering as well, after all you could wager a ton and not lose much but you could also wager just a bit and lose it all at the same time as well.
You should be careful about how much you can wager and why it should not be something that is profitable for you if you wager that way, I personally do martingale and stop after 5 losses, I can regain that back if I am lucky and if not at least it postpones when I will fail, that is why I do get a decent return and not lose quickly but I always end up losing it all, this system is designed to make you play as long as possible while losing all of your money, it is not a good design to gamble, but it works for this place at least.
