Quoted from Luckydogg420:You might not like the idea of Bitcoin, but the technology used to create and control them will change the future
Agreed. Blockchain has applications in many industries, where tracking history, sharing complex information, and security is important.
If someone could figure out how to use it to secure credit history and identity it would truly be a breakthrough.
Unfortunately, use as a common currency in its current form is unlikely for a variety of reasons:
scale - mining gets exponentially more involved as the items age. Do you really want to track a coins entire history to buy a piece of gum or other end-user purchase?
backing - I don't trust the government, do you think I'm going to trust a corporate entity to back my money?
the nature of purchases - the volume, rate, and size of most purchases & currency transactions don't need the properties that make blockchain unique: tracking history, sharing complex information, and security
Blockchain is at the peak of the hype cycle right now. If you want to invest, look at companies that are developing real world solutions based on blockchain.
Buying Bitcoin today is equivalent to investing in Pets.com in 1999.
