For today the cource of an etherium makes about $860 it means that one OAK token is hardly more dearly than $1. Now it is still profitable to invest even at this stage. Because the declared price of the OAK token is $ 1.4
And don't forget Acorn still doesn't announced main sale bonuses. May be it will be tasty.

What will happen if by the end of March the price of ETH is 2000$ ? The price of one token will be 2.5$ ...
This was one of my very first questions as these fluctuations can also be a problem once the platform is up and running.
To work around this perhaps with main sale, the team should just specify $1.40 per token with an on the spot ETH rate when buying. I've seen this done with other ICO's.
