Even if there is a drop I doubt it will go below $650.
Chances for this to happen are slim, but not impossible. I personally think that we'll come very close to $670 where after that we'll slowly see the price hovering up towards the $700. These movements will most likely repeat for the rest of this year.
Still I'm glad I put all my BTC into alt-coins when it was around the $725 mark.
So you don't have a single Satoshi right now? I find that really hard to believe. I know people like to diversify their portfolio where a certain part of their BTC goes into altcoins, but I haven't seen anyone so far going all in on altcoins. May I know what altcoins you have chosen, and at what price you opened your positions?
I still think we will hit $750 sometime in 2017.
If we don't experience any more drama from "hacked" exchanges, then we can go even higher than $800 in 2017, but we can't rely on this as it is just speculation.
