I think your data is incorrect. I following all governmantal news sources and never heard of legalization. All officials deny that bitcoin is a mean of payment. So far officials are going to legalize mining (with taxes) and ICO (with contribution limits). There are contradictory news about trading. Ministry of finance wants to legalize exchanges, central bank wants to enable only tokens and ban coins(which doesn't make any sense as always).
