Considering how ETH began to grow, it may make sense to transfer part of the BTC to it, but it is not known whether the price of ETH will continue to rise or has stopped. I think part of the BTC can be exchanged for ETH, but not a large part, so as not to lose profit in case the BTC price breaks ahead.
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.
