BTC will have been stronger by the end of the year, but I'm not sure if other cryptos will follow the trend.
Anyway you can follow the statistics on cryptocurrency, subscribe to their respective communities, check coin360 daily.
I suggest Litecoin and XRP.
Out of thousands of crypto coins we have few best recommended coins for which the market is demanding and have high values due to this demand. The investment of these coins will have a huge profit at the end and will payoff when it comes to bull market and you sell it on high price is what other traders did and millionaires right now.
