I doubt it. No one will use bitcoins anymore because they won't have the network effect required to extract value from currency. You can say you have Six Bajillion Bonkers Bucks, but unless a critical mass of others accept Bonkers Bucks as a valuable currency, it's worthless.

People want money because it's a token by which they can gain control and power over things. If bitcoin stops becoming this, no one will want it anymore. Bitcoin is nothing by itself, and if you can't get it into dollars, no one will want it anymore because there won't be enough people with enough respect for an independent bitcoin to yield up the control or power currency holders are trying to acquire.

Drug dealers use bitcoin because it facilitates online transactions without requiring the endorsement of a credit card company, payment processor, merchant bank, and so forth, and because they can cash that currency out for U.S. dollars, which they use to give themselves control and power.

No one wants bitcoins of themselves. I run a software firm and have tried to offer my employees partial payment in bitcoins, and none of them wanted it. If these guys don't even want to get into that game, what do you think the normal person will say?
