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.
Are you short time or long time investor?
You need to pick the coin based on how long your investment will be,if you are a long term investor definitely go for the ethereum because Ripple price bump looks temporary and it will hardly fall soon.As you said ethereum price is very stable over the past so the risk is less when compared to ripple investments.
I think long or short investment time is not necessary because both coins are successful investments when the market is green. Personally now i prefer ETH more, the reason as you say it gives me a more stable feeling.
