I am a window shopping girl. If have 1 bitcoin, I want to buy some clothes or cosmetics.
Bitcoin is unpredictable.. anything can happen in the future, you may never know and can't ever predict by simply looking at the BTC Chart..
For instance, you sleep tonight and you wake-up in the morning and you see that the BTC Price just boomed upwards (too high) or went downwards (too low)
There are Ups and there are Downs.. still we always have trust on Bitcoin..
But we need to act smart as well... investing too much in anything in bad according to me... a sudden hike may make our life discomfort..
So to be on a safer side, always withdraw some BTC when the price is way too high and when it's down simply don't touch it..
That been said, considering the various Bans/Restrictions across few countries (including mine, i.e. India), if i have 1 BTC and if the price of BTC is quite high then i would rather encash it in full or at-least a part of it because i am a believer of "Something is better than nothing"
Once you have the money, you can make it useful in real life for your needful purpose..
