It's a **really bad idea**, so much that I registered just to warn you (I live in Venezuela). When there was a severe shortage of cash the government blamed it on banknotes being [extracted through the Colombian border for sale at a profit][1] and "hoarding". Arrests were highly publicized, which additionally helped support the conspiracy theory of an "economic war" waged from abroad.

Now imagine a foreign-looking type caught with a heap of cash: official news outlets are going to have a field day with the [arrest photograph][2]:

Best case scenario, you'll spend a few hours in "the little room" and relieved of everything valuable on you by the local authorities.

I agree that they're pretty, but please just take a few of each. If anyone asks, it's what was left over from your daily purchases.

**General advice**: don't come without a trusted local friend willing to accompany you everywhere, preferably in a car. I'm not exaggerating: Caracas has the 2nd-4th highest murder rate in the world, and $100 can feed a family of four for a month.

BTW, the photo in your questions illustrates the amount of cash you needed to buy that toilet paper roll before it was redefined to have 5 less figures (1 new "Bolívares Soberanos" = 100,000 old "Bolívares Fuertes").
