Maybe moving some % of BTC into ETH is a good diversification strategy, while it's cheap?
All of the coins are cheap or very low for now. Well, i guess by moving it maybe a good strategy to gain more if eth price rise anytime but remember that btc will also be rise anytime.
Everything is very cheap. This is right. However, I would never change Bitcoin in Ethereum. ETH will always follow BTC, and I do not see any sense in these changes. Just go on holding your Bitcoins.
