recently ripple reached 1 usd and is predicted to go upto 5 usd by the end of next month.
while eth has rose 100usd in the past week and is being quite stable.
ethereum though not as accepted as bitcoin but still can be used unlike ripple.
so my question is whether i should invest in eth or ripple given i may need to take out my money back any time.
I think the question that you should first need to hear is, how much do you want to invest? And if so happen that you have an enough money to invest, then you do not need to be bother for choosing which one is the best. Both are good for investment so you can make 50-50 or 40-60. This is a wise move rather than choosing only one. It can save you from a big crash is their is a possibility to it. Better to make a wise move specially it is all about money.
