now, I still believe in bitcoin (BTC) and Ethereum (ETH). I am sure both of these coins have good potential, and their value will rise by the end of 2019, hopefully this will happen.
In general, you are right in choosing Bitcoin and Ethereum for the investment. But it seems to me that even living will be much more productive, especially if you compare the current prices, these are the prices that were in 2017 and started in 2018. The difference between ethereum from 1300 and 150 dollars is almost 9 times, while the difference Bitcoin from 20,000 dollars to 5,200 dollars is almost 4 times. Thus, if you invest today in ethereum, then your contribution will increase almost 9 times when the market reaches last years level.
