i started mining now, I am planning to hold about 50% for long term and sell immediately the other half. I am expecting ST gain @ 39% for the ones that I sell immediately (assumption) and hoping that I can get taxed for LT gain for the ones I will hold over a year. Do you think that is possible?
This will depend upon the country im which you belong because if your country legalized the use of bitcoin it well be taxed as per regulation rules. If you change your bitcoin to fiat thru your local exchanges then tax is already expected then if you earned thru bitcoin of course it will be declared as income tax in which impossible to hide when we go through local exchanges.
