I guess focusing in sports betting is just the right thing to do, at least you can just stay at home, study the games and analyze it, very fit for the current set up under the covid-19 pandemic.
I would add playing poker to that; playing and, of course, studying how the best current pros are doing it. I'm watching channels like World Poker Tour, partypokerTV and PokerStars on a regular basis, and it works for me. It's really entertaining to learn something from the best, and then apply it in practice. But the keyword is "entertaining" here. I'm not planning to make my living from playing poker. Although I consider poker the most skill based game around, there's still too much luck involved to rely on it as a source of income.
It really depends on how you treat gambling or a certain game, if you don't like to venture on a higher risk, then treating it as an entertainment is more than enough to enjoy and be thrilled in gambling.
Poker, yes it's a skilled based games but I think sports betting is easier. Both, poker and sports betting require researching and learning, if you want to be successful in it. It depends on the person what is easier to them, and to me personally it is much easier, and, what is more important, much more enjoyable to watch top poker games on YouTube and learn from the pros how to play, than to research about injuries and disqualifications in order to be successful in sports betting.
But that's me. I realize that for some people watching those poker games may be as boring as for me researching about injuries and disqualifications, and sports betting suits better for these gamblers. I know that millions of people enjoying sports betting, and surely they have their reasons for that.
