Most of the people around the world need of the lawyers advice to secure their assets.This problems was occur with the people,where cryptocurrency was a taxable one.The crypto currency taxation was the new way of taxation was imposed by the government now a days.Many developing country government was started to impose more tax on the traders now.Now crypto market already trouble the people,this taxation was a double burden.
Not totally a double burden unless if you do touch up centralized platforms or services then you would definitely be having that taxation problem specially if the government where you do live will really be serious on cracking and tracing down into those people who do get involved with crypto.
@OP, if you do look for a lawyer then you would definitely need to see one locally.Dont ever tend to look online, nothing beats off when you do have some personal or face to face approach on someone
you do really need up.
Knowing that this had to deal with Poloniex, then i highly doubt that there's some lawyer will able to handle out such case or situation.
