You didn't know this?

No, it doesn't scare me - it used to be 2 years :D

In case you are right and the price of HIVE goes up, how can you be sure that its value will not fall until you withdraw the entire requested amount.

I have been caught without liquids many times, but currently keep some liquid just in case. However, I am also going long on Hive, so missing a pump or two doesn't matter much. What I have found is that for most, they sell their Hive at the highs, but don't buy back at the lows - they think they will always earn again - eventually, they won't.
