Paying taxes is not a voluntary thing to me, the law is enforce to require us to pay taxes and failure to comply with it will make us liable for tax evasion. I believe if you can hide something that is your privilege not to pay taxes like what is with the scenario here in bitcoin world, we earn but the government does not oblige us to pay taxes since bitcoin is not regulated in our country yet.
Yup, that's why they didn't collect taxes is that. Bitcoin is not regulated here in the Philippines, which means even if you earn. They will not interfere, vice versa, if you are scammed. They will not responsible for that to get your money back. But, if they regulate the Bitcoin here. We can minimize the instances of Scams and our protection against them will be established. So for me, paying tax is Worth if our security will be observed.
