It seems like bitcoin doesn't give a surprise at the end of the year unlike the end of the previous year. Every end of the year, bitcoin has given us a very good surprise by breaking the highest value of bitcoin, but at the end of the year it looks very different 
.
You are right every end of the year bitcoin gives us a very good profit and unfortunately the year 2018 is very bad year for us which we can't make more money through crypto or bitcoin, but we need to be patient and wait for the next year because the crypto expert says that the year of 2018 is a very good year for people who invest their money in cryptocurrency and 2019 will be a very best year for us which the cryptocurrencies provide us a high amount of profit..
