This is crypto, willing to bubble or not it crypto run by itself because here there is no party that regulates the growth of coins, free coin moves. I do not agree if you discard your ETH to get back to BTC, keep your ETH. Please if you want to go back to BTC, but do not throw your ETH. Remember the ETH will not disappoint its customers, ETH also has a very strong potential to achieve the highest value, because ETH grows every day.
