Here is my outlook for the major cryptocurrencies:
1. BTC: The prices will continue to increase and a new ATH may be reached by the end of 2019 or by 2020. The dominance will continue to increase and may reach 70% by the end of this year. But one concern I have is regarding the transaction fee. It has risen by more than 10x since the start of the year. Another 10x increase would be catastrophic.
2. ETH: The exchange rates are still lagging behind the ATH. The poor health of the ICO market is probably pulling ETH down. The Cryptopia hack also played its part.
4. BCH: Holding well as of now. In case the BTC transaction fee spikes again (like what we had during 2017 Dec), then this coin can rocket upwards.
7. BNB: I would consider this coin as overpriced. A correction is due.
I think the coin above is still above the standard of the average even though indeed when Bitcoin experiences a bull run, all coins will also be weak in growth.
Although some people say correction to this day is quite worrying, this should not be an obstacle and should be used to take at least a portion of it.
