yes ETH is worth much higher than it really should be.
no BTC is far less than it really should be worth.
but you should break down that adoption to see what it really means.
for BTC adoption means 2 different groups.
1) new investors who saw the potential and the good performance so far and have invested to get rich over night. these contribute to the rise a little but will never sustain the rise because they will dump and cash out as soon as they reach their desired profit or as soon as a FUD is heard or a dip happens.
2) the real adoption. which is all those people who see bitcoin as a currency (on top of being an investment). all the merchants that have been adopting it as a payment method for example.
for ETH the adoption means 2 groups:
1) the same as 1 above, those who thought they can get rich over night and will dump as soon as they get their profit or the price recovers because they bought in a bubble.
2) those who want to participate in an ICO. and this is the worst thing. all these little buys push the price up and all gather inside 1 pocket, a pocket that will dump these free coins on the market eventually. and when the ICO scam season ends this type of demand which was 90% of the price rise will be eliminated.
the price rise created a FOMO feeling for ETH which causes a rise for a short term and it disappears just as fast. and most of the people who invested are currently in a loss. they mostly went down to -50% loss and they have recovered back up to -20% now. this is the performance that majority have seen so far in the past months.
i can name at least a dozen coins that were profitable in the past week alone and this is the trading board you are in by the way.
