I understand you, I know how you feel, it is good to see BTC that is in a balance of 0.01btc, and that the price is above $ 60k is something fabulous, and when you check the equivalent in USD it is something phenomenal, however I think Like you, I like to make bets in the casinos only based on cryptocurrencies and as a last option, see or bet in USD. It is like a protection measure, because if I am betting on cryptocurrency I don't like to check its equivalent in USD because it is going to suggest me and I don't like that, then I will deconcentrate and I cannot do everything with freedom.
Yeah it is just another extra hassle, I keep doing that every time I started to gamble, there is really nothing worrying about it and I will not change my casino because of it or anything but it is that tiny little extra work in some places that makes it hard. I prefer to do stuff that do not make me work for extra things but this is just way too tiny and I do not care about it at all.
However for some reason when a place has it, it just makes things a lot easier and I feel a lot more happier there, not having it is not bad but having it is certainly good. Otherwise I just check how much my bankroll worth at that moment, then divide it to 100 and then start betting with 1/100 bets and keep doing that for only few hours and leave, it is just fun for me and I do not care about the money earned or lost here, I just want to relax and reset my mind.
This technique is very good, really what I look at sometimes a lot is the price of BTC, because I know that it affects cryptocurrencies in general, days ago there was a drop in BTC, and since most of them bleed, in USDT I don't like to see the values, I only focus on trying to multiply the coins I have but without seeing their value, if I lose much less I see the value in which I lost, maybe that causes less stress, and as you say it is better to play relaxed without problems, just like that the mind clears and you can think much better or at least react when you are playing.
