So I have a question, is there anything ACTUALLY backing up btc?  I understand the process of obtaining btc but I might not have read in enough.  I noticed blockchain.info doesn't get any support, and that's where btc comes from, right?

If you aren't receiving any support from a website that is the center of btc, why would you put all of this money in to it?

Is it possible everyone could wake up one morning and blockchain.info be gone? What would happen to btc?
