In early December 2017, some pirates stole 4700 Bitcoins worth $ 80 million from NiceHash, the crypto-currency platform. This is the last of a long list of similar events, accessed by hackers who can access accounts and make large amounts of money.
Hackers own Bitcoin, a treasure that speaks their own language, a treasure they can use to capture their fortune. According to Kaspersky, 2018 will be the year of malicious code that misses accountability. Capturing millions of computers without permission and using them to dig in crypto may be something we will hear next year.
2018 also offers a challenge to Bitcoin's infrastructure. The difficulty of handling crypto-currency platforms with traffic summers spreads a little distrust between buyers and sellers who witnessed the hours lasting for hours even though orders were not triggered.
I took my BTC investments for these reasons. The best option for me now is steem. Due to the current fluctuations, the price is low. Most importantly, we already know the true value of Steemit users. I steem and trust myself. I would recommend the same to you. @cyrptographic
