Hello,
i thinking about to invest some "bigger" amount of money into one of these 2 currencies. But i really dont know in which one. ETH should be more stable and safer?
If u had for example 1000$ and you would invest, which currency of this both would you take and why?
Well, I think it's not worth thinking about, there are so many advantages of the original before fork, and the future looks promising. So invest in real ETH, this will reduce your risks and give you hope for the future.
