Do you bet big like 1 BTC in hope to win 50 BTC with a huge risk or do you do small bets?
Bet big to win big? Or bet small over a long time to be safer?
I've been on both low and high end of the spectrum. Although I have never gambled 1 BTC, the largest I've ever gambled on a single bet was 0.25 BTC but I won 2.5 BTC that day lol
Nowadays I stick to betting 0.000125-0.04 BTC, all depends on how much my balance is and if I'm playing for fun or to test out new strats

That's a big downgrade in terms of your betting amount, now I can really tell you are playing for fun cause I was really surprise a high roller like you changes to betting small amount now. That kind of attitude would not make you addicted in gambling since you are flexible knows how to play for fun.
I could not imagine time will come that I will be better like a quarter of a BTC, maybe I am desperate to win if times comes I can do that.
