Yes, $ 6 is a small amount, but compared to the amount of money I’m going to lose, it matters so I will definitely try to save it. In addition, do not forget about the execution time - usually casinos require several confirmations, and I think that in modern conditions it is irrelevant to wait for a transaction to be completed for almost an hour.
I also do not want to shelve that amount and don't want to wait for hours to roll the dice, I don't have the luxury to wait for my transaction to confirm, it's better to use Tron I can play within 5 minutes or less and I have to only spend 1 to 5 cents for my transaction, for small players like me that $6 is worth a lot, there was a time I play with only $5 in my dashboard.
Yes, many players play on micro stakes just for fun or to test some strategies in real conditions (this is very correct since bet simulators can give incorrect results). Obviously, they are not ready to pay a commission comparable to the deposit being made.
