According to this video,
https://www.facebook.com/cnbccrypto/videos/1688689147880991/Bitcoin is considered as property and therefore whenever you sell your BTCto cash, there are two transactions. You first sell the property to cash value then what you gain from the sale is used as cash. These transactions are therefore taxable.
For HODLers, if you cash out it in less than a year then it would be considered as income so theres tax for that. If you hodl for more than a year, then IRS will consider it as 20% capital gains.
I think this has two different point of view depends upon the philosophy of every bitcoin hodlers and supporters so it could be acceptable as property and/or it could also not a property.
When we talk about property we are talking about for something own by a person and stands as a source or assets of his/her income. It is also a thing you bought or received as a gift, and far as I know money is not a property but the product of property or of the source.
