it has a possibility that the price will goes higher at the end of 2020, i think we can see $800 at the end of the year if there is no bad thing happened during the hype. currently the price at $466 and it is still keep going up because the volume is really high and people will probably following the hype train that people will buy even more ethereum.
No one is impossible all is gonna happen if they want to reach on a higher price. And if we have trust for etherium there will be a chance to followed by bitcoin all we can see right now bitcoin are in top and start to increase more the price so its same for etherium are trying increase the price more maybe as you said in the end of this year etherium will be take the price of $800 and well let see if this will true.
Your last statement shows some level of doubt, but as for me, it is going to hit it and nothing is going to stop it. Ethereum is seriously bullish this time, most especially at this time of rise in Dedi and with the serious use of uniswap, it is nor going to stop until it reaches that price.
