If you feel doubts on your next step, I'd rather have to stop it before you face regrets.
Yes, it is quite tempting to see how ETH takes a move by now but the question if it will stay for long or just a week and it dumps after. We're the risk is too high if we are planning to chase ETH after BTC. We have already in the right position and we are in good actually, never leave it.
I agree, this option makes sense, but I think that you can take a chance and change part of your BTC assets to ETH, but I do not exclude the possibility that the price of ETH may unexpectedly go down and cause losses. Although I have recently seen a lot of positive news about Ethereum and the popularity of applications based on it has also grown slightly, perhaps this provoked an increase in the popularity of Ethereum.
