ETH is now in an extremely low position. How good is the idea to buy it now?
I don't know why you have a title like that,
time to change BTC to ETH?
you never convert your Bitcoin to Eth or your Ethereum to Bitcoin, there's no logic on that, this is the top two coins in the market, any changes in the market will show the impact on these two coins because this is two most-watched coins in the market.
I always tell my friends to always have these two coins as their main portfolio how the these two coins perform will always have an impact in the market.
True! Both btc and eth are co-related in terms of market behavior. Except any strong market indicators, both btc and eth generally moves in same directions. When one is bullish, other is bullish too and vice-versa. So there is no point shifting between these two really.
They are correlated that is true but all the markets are correlated in some way or form to bitcoin, the question is if there is enough difference between the movements of each coin to guarantee profits if you have a successful trading strategy? And the answer to that is yes, there is enough difference to make profits by converting your coins from ETH to BTC and from BTC to ETH, some may wonder why you would want to do that and this is done to try to get more bitcoin than what you had at the beginning.
For example if you invested one bitcoin and bought 50 ETH with it at a price of 0.02BTC for each ETH and then ETH went up in price and you sold each ETH for 0.04BTC now you got two bitcoins instead of one.
