My suggestion is: Holding Ethereum and wait for good price to take profits. After that, swapping your bitcoin to Litecoin, and using Litecoin to move your funds around. That way, moving funds via Litecoin, will help you to avoid delayed transactions on bitcoin network, and high fees when bitcoin network has too many unconfirmed transactions. Litecoin gives you lower transaction fees, and less network congestion issue. I have a big love for Litecoin due to its advantages to move funds: cheap, fast, and nearly zero congestion.
