If you're a profitable sports bettor or any casino player, you should make sure to save money for tax time.
Every 2 weeks I calculate my profit on and put 30% away in a ALLY bank savings account that earns 4% APY per year. This way I can earn a little interest on my gambling tax payments.
I also will preload 15% of the prior years winnings into the account, so that I have a good baseline for expected tax. For example, If I made $100k the prior year, I would put $15k at the start of the next year, so that I am earning 4% APY with the money I expect to pay in taxes when I make another 100k. (I will also add 30% of the profit per 2 weeks like mentioned above)
This means you are a profitable gambler unlike many here that sees gambling just as a way of losing money. I have continually stated that many people are making decent money from gambling, at least a know a lot of them. Glad you put this out so others will know that there are
HUMANS that actually win gambles.
What are your strategies?
There is no tax for gamblers in my country. Unless you are gainfully employed or you own a registered business, you are not taxed, not in crypto or gambling or anything. It's actually a nonchalant attitude on the side of government which somehow makes the citizens relaxed.
Arbitrage betting will not get your funds stolen if you live in the United States and are only using books that are regulated. If you use crypto sites, then you would be risking the sites stealing your money.
I don't think I agree with you on this because their are many reputable casinos that accept cryptocurrency. They are even dominating the gambling industry so if you are still stocked in the old ways, then that is your choice. Crypto has come to change a lot of things and gambling is just one of them.
