Here, the tax you pay on winnings is 30%. You can try to ignore it but they are hunting down people that gained money on blockchain.
Besides of that, most of the news I see is:
- monero miners installed as malware
- bitcoin broke through the 10000$
- bitcoin falling like a brick
- bitcoin servers stolen
- tax hunt on bitcoin investors
- complains about fraude in cryptocurrency
- bitcoinmining uses a lot of power
