It's nice that a tax was introduced (becuase it means cryptocurrencies are legal now) but 42% is really much. As such, I'm wondering whether this legislation will help because people may still try to avoid the law due to the high rate. Governments have to come up with reasonable rates, otherwise regulations will not work.
I'd prefer it to remain in the gray zone than be forced to give away half of my earnings (as a miner). Historically, Jews always knew how to make money and were seen as greedy people so it doesn't surprise me that their government is following the same path.
That's why I'm against regulations. They never bring anything good for the people. A government involvement always means that you'll get robbed while they're trying to make you feel happy, like you're doing a good thing, contributing and all.
