You gotta be fairly ill-informed to consider ETH as some kind of meaningful threat to bitcoin when considering the various upcoming scaling and innovative improvements in bitcoin's near future (including the havening of BTC's new supply situation, too), despite some of the recent ETH pumping efforts..  In other words, if you are looking at these kinds of short term price moves, you are getting a bit distracted by the trees rather than attempting to see the forest.

You are gambling considerably if you either hold significant quantities of ETH or you are investing in significant amounts into ETH at this point (in comparison to BTC)... Sure it is possible that ETH could 2x or 3x again, but it's downside seems a lot greater than BTC's downside potential.. .think about it? 

From our current price point, which one is more likely to reduce in price by 50% or more?  ETH or BTC?    I am not sure about what odds I would place, but it seems pretty decent odds that ETH is more likely to go down 50% or more rather than BTC... maybe 90/10 - ish?

Currently, I don't have any money in ETH, and my opinion is that if you are brave enough to put any more than 10% of your total crypto holdings into ETH you are gambling in a fairly irresponsible way with your personal finances that is more likely than not to end in significant financial losses.

Surely as individuals we have a right to exercise discretion over our own personal finances and the risks that we are willing to take, and with any gambling there is a probability that your position could pay off more than a more conservative approach, such as mine.
