I think it's too late to invest in bitcoin. Since the price of one coin is too high and no one knows what will happen tomorrow.
OMG, the oldest post in the book of whining. Don't buy a whole coin! The gain is proportional to your investment. If you put $100 into it and it goes up bu 10% you'll earn $10. If you put $1000, you earn $100, and so on.
It seems to me that the more realistic forecast of the bitcoin price will be $ 2000 by the end of 2017. Bitcoin began to grow, but it will not be able to grow so rapidly during this time, there will be small price reductions.
I think so too, it won't break $2000 this year. It can even go down a bit depending on the news.
