I think bitcoin and ethereum altcoin are good for us now, because now the development of both is also better, so I'm sure the future of bitcoin and ethereum is also a good way for us to last.
From the current market scenario ethereum is the hottest trending coin for 2019. Last year it was predicted to be the year of ethereum, but market didn't gained enough support. To the expectation the price began to decline drastically and the same continued with 2019. With the upcoming hardfork it is predicted to make a big change.
