If i was in your position, i will definitely leave that in btc and looking forward to buy more ETH+BTC according to own analysis. Every analyser/traders are having a bad to chosing what to do because of the upcoming golden cross events of btc price. In simple word,(1) we can see bull run if btc able to cross the $10k price range and make movement above $10k as a support. (2) Else we can see a 30-40% correction which indicate BTC as well as ETH price will drop . For (1) no condition, i will try to buy BTC or ETH part by part using the risk management of total funds. And for (2) no conditon, i will try to buy both BTC and ETH in the deep. It's just my opinion, everyone should try their own research and make own strategy.
