Profits? What profits? LOL.
Jokes aside, this is really nothing surprising. Profit from trading still falls under "income", hence chances are, there are going to be taxes.
Is it good or bad? It just probably completely depends on what the percentage tax is. If it's <10%, then it's probably fine? Depending on the trader. But I've read somewhere in the past that there are some countries that taxes pretty much around 50%. Now THAT's bad.
Maybe good? For if government charges taxes on it, it will be a sign that government better accept it.
Not necessarily means that government will accept it. It's income, hence it will be taxed.
