I prefer bitcoin because it is faster and more profitable. the current bitcoin price is much higher. I suggest that you look for opportunities to get bitcoins at low prices if you want a bigger profit.
yes indeed that's true but in my view better choose both rather than pick only one of them but if you have to choice between them then bitcoin is more potential rather than ETH as you can see bitcoin has already reach all time high and still possible for next several month bitcoin price will surpassing the current all time high so invest bitcoin indeed profitable
