Be ready and aware that 2018 is the year of regulatory reckoning. Countries around the world are trying to determine how they are going to treat cryptocurrencies. Securities and Exchanges Commission (SEC) has halted several ICOs and hinted at the need for greater crypto regulation.
There is no doubt about that and government will continue to increase their control on the cryptocurrencies by implementing the regulations.
I am into cryptocurrency because of freedom, I can't deny to myself that I have worries regarding this issue. And as an investor, I really have no choice but to stay with crypto once the governments around the world have control to cryptocurrencies (if that became possible).
Government can not have total control on the cryptos so there is nothing to worry.
So as much as we can, also invest with physical properties with what you've earned. For we don't know what will happen next with our money in the digital world.
Obviously, its always advisable to invest into the diverse portfolio. Its very risky to put all the money into the single asset.
