Im still newbie here and Im curious if some reliable sources predict way back 2016 that bitcoin and eth will increase 800% before the end of year 2017?
If yes what's hes/her prediction before the end of 2018?
If someone with a fortune ball could tell this then everyone would have been millionaires. Some people do technical analysis and were saying a formation of some cup and handle which would indicate bullish trends. But again these analysis are made after the price increase rather than before.
The best bet for price increase is to invest yourself in coins that you believe are really going to sustain in the future due to their technology. Small coins like REQ will go way higher once they are implemented and developers do well. If you are regretting of not investing in ETH, you can try ICX and I feel it is going to be like ETH sooner.
