I think they are afraid of btc because governments see the dangers of btc threatening to manipulate their printing rights. So governments are trying to propagate btc's virtual value. The world's money every year is inflation because the government prints money too much compared to the actual needs of the people, while btc has finite numbers. When btc is more popular, btc will be like gold or diamond.

In my opinion, five types of tokens will growth in 2018:
- arcblock
- seele
- polymath
- bee token
- dadi

I think Lunar New Year will affect the current price of btc because of the rate of people investing more in btc from East Asian countries have Tet holidays with the Lunar New Year as Vietnam, Korea, Japan, Singapore. People in these countries usually spend big money on Tet holidays, so they usually sell btc to their own currencies, leading to btc prices going down on this occasion.

The reason I invest in cryptocurrency is because it gives me big profits in a short time

Bitcoin is more convenient than cash for the following 3 reasons:
1. Bitcoins are not inflated by the government, the bitcoin value is increasing over time as its limit is only 21 million in volume.
2. Easy to exchange when traveling through countries accepting payment of goods by bitcoin.
3. Fast, no fees and the government does not know what your income is so it can not tax your income.

When will the tokens come to exchange?

I think dock.io bounty is good because dock.io is a good project which can growth for long-term!!!

Bitcoin is an application of blockchain technology. The blockchain is a breakthrough of humanity similar to the invention of the internet. It is the leading security technology for the future and the most application in banking, information security.
