The market in the early days of 2018 is very complex and difficult to predict, you can see that the price of bitcoin and altcoin are constantly decreasing and there is no clear signs of recovery, so the cs Successful business you need to have specific and accurate plans. Bitcoin prices are fluctuating in very small amplitudes and have strong convergence, so capitalization is down so I think bitcoin prices will continue to fall and altcoin will be the same.
For me Bitcoin and eth im sure that two is theres a good future because of people using and investing and theres a big chance that grow up the price and i think LTC is theres a possible but not the same of bitcoin and eth but LTC is good also and slowly to grow up the price...
