I still dont know anything about that matter regarding about crypto taxes is included in the train law.
There's no such thing as Crypto Taxes, Any income whether from cryptocurrency or not we need to declare this to our ITR but due to weak enforcement all Homebase and Freelance workers can get away without paying a single centavo to the government.
If you want to be on the safe side, Declare your income from cryptocurrency but only declare an annual gross income of 250,000 Pesos to enjoy a tax free incentives provided by train law.
Because soon BIR will start cracking down all those homebase workers with unexplained wealth that didnt pay any taxes or submit their yearly ITR. Your deadline is April 15, 2019 for 2018 ITR.
