Online betting is my preferred way of betting because anytime and anywhere you can quickly make a bet using cryptocurrencies as long as you have access to a pc or phone with a stable connection. I don't hate live betting but it takes too much effort to do regularly compared to online betting it only takes a few clicks/tap to gamble. The cons in online betting is that it can lead you to chasing your losses and casinos can run away with your money .
What do you mean by Live Betting here?
I guess what he meant was going to a casino or place where the event happens since OP mentioned racing.
