My answer is maybe....
Maybe you can donate some to charity.
Maybe you can sell some and buy some altcoins.
Maybe you can trade buy and sell to make it multiply.
Maybe you can hold until such time you can't hold it anymore.
Maybe you can sell now and buy more later.
Maybe you are serious or not.
Maybe you don't have 12 ethereum or you have.
Maybe you are hesitant because of ethereum situation.
Whatever the maybe you in, it is all depends on you. I wish for the best.
