"The Norwegian government stated in February 2017 that they would not levy VAT on the purchase or sale of bitcoin.[135]"

Hi, hope you guys are keen on helping me.I got that information from Wikipedia.

By" sale " does it mean selling your bitcoin for money would not be taxed or no need to inform the tax offfice? That sounds too good to be true.... I know you don't need to pay VAT for buying Bitcoins in Norway which is excellent for Bitcoin buyers in Norway . But how do you define " sale"  selling and trading? anybody can help to explain it? Thanks in advance.
