Welp, time to sell.
The price two days later: $234. Up $84.
Required reading for prognosticators:

At $20 I feel there would be so much renewed demand from such a low price it would never stay there, almost an immediate rebound.
There seems a Sunday-Tuesday surge in prices, perhaps as people who learned they wanted some over the weekend in Asia-Europe-Americas get their funds in and make their purchases. So Tuesday may be a better time - I have a hunch it'll break $200 by then.
Still, as suggested in my downvoted reply to the above 'sell at $50' comment, $500 would be a better time for some profit-taking.
