Ethereum at the end of 2018 doesn't reach $ 300 and even reaching $ 200 is very difficult. But Ethereum has shown a positive sales trend and prices have started to rise. And now in 2019, I think the price of Ethereum will start to increase because Bitcoin is also rising.
Still not sure about this but Im confident too that ETH will rise again. Now, I dont want to set any time limit for ETH because I know it will rise in time. The price dumps again, so try to buy and hold. Almost all cryptocurrency will start to recover this year, just wait and see what will be the best trend this year.
