Recently I got a CoinBase account and I started buying Bitcoins and ETH. In the last couple of weeks due to China, Philippines and Japan legalizing it as well as Trump's impeachment talks have lead to over 264% growth in these two coins. My investment has pretty much doubled.
I feel that this trend will continue to grow. Purely, because BTC and ETH are gaining traction as more and more countries legalize them, following China and Japan. This will increase the demand for the coins. Also by 2020, the number of bitcoins paid-out will be halved. As BitCoin reaches the 21 million mark, and the adoption goes higher, there will be demand greater than supply leading to higher valuation of Bit Coins.
