Selling istead of waiting...sell to spread the market and more possible income..
It depends if you want to sell but right now if you think that you need to sell, go for selling some of your bitcoins.
But for me, it's going to be a good thing if you are not going to sell all of it. You may sell some of it if you want to help the adoption in the market.
And it doesn't mean that you are going to wait forever or a longer time, it just depends on your satisfaction.
If you have enough cash to use then just don't sell your btc.
