I think we'll keep seeing the growth of the gambling industry specially online with the general growth of internet use

lotteries will probably keep going as a trend as well, on the last day of 2021 we had the biggest earnings by a lottery in Brazil, 1.2 billion reais (around 210,417,600 USD) earned with a 350 million reais distributed as a prize (around 61,371,800 USD)
quite impressive!
