No one is arguing about price of ethereum here. And even if ethereum is directly connected to REAL itself so this isn't offtopic. If someone wants to invest in REAL they need to pay FIAT for ETH (If they don't own it already)...
You invest with ETH, meaning that what you have today, it may be less tomorrow, so nobody can be sure if one should invest now so they don't lose REAL tokens, or invest tomorrow or any other day when price is rising, because it could easily go down more, and besides, REAL is based on Ethhereum, and now REAL is in an ICO, so eth prices will be VERY important here, because it concern the investment and the token, y REAL wasn't in an ICO, then I would agree to a certain degree that it shouldn't be discussed here.
