Some gamblers think if the price is so expensive it would be difficult to get profits.
How about you?
If Btc price is expensive, so does the transaction fees.
There were numbers of gamblers who has been struggling to put Btc into the gambling website due to high transaction fees and clogged mempool. It has been greatly affecting them for missing some of the game and sports they like to bet because of the confirmation waiting time which usually takes a short while with minimal transaction fees, but It's different today when Btc is rising.
I don't see anything difficult in making profits during Btc bullrun, IMO it's still the same, the only that's changed was the value of the fractions of Btc that you're betting.
I have seen the same, people are complaining that the fees are too high and t is taking a very long time to get a confirmation and without it they cannot gamble at all, while some may not consider this to be a problem but if you are looking to make a transaction with a low amount of bitcoin it is entirely possible the transaction cost is going to be bigger or at least be a significant part of the value you are trying to send in which case it does not make a lot of sense to send that money over to the casino.
