Bitcoin is easy. get an account at coinbase site. However, for peeps that trade back and forth with crypto buying with crypto may be ok. I dont think the average person would want to. Like a stock or any commodity on the market, each time you buy, and then sell, ( by using bitcoin you bought for the purchase) it is a taxable event that should be recorded on your taxes.
When all this crypto first was getting hot I wanted to buy a currency that was difficult to source a seller for that took US currency for payment. So, we decided to use a digital currency that we already owned, Ethereum, and put it on a site called "shapeshifter" that would transform your Ethereum into something the seller accepted. Well, that sale of Ethereum generated a small tax headache paperwork wise. It was a long term capital gain at least...and all my crypto is now recorded, and paperwork done so when it is sold,
reporting will be much more simple. Simple is good for Bubba.
