In 2017 it was not the Lightning Network or any of the use cases for Bitcoin that drove its price to almost $20,000. It was pure speculation, FOMO, a new get rich quick scheme and probably a strong price manipulation conducted by whales and investment firms. Bitcoin will never replace fiat in my opinion. It will have some other purpose. I do believe though that in a decade or two more stablecoins will emerge that would be used world wide in all sort of known and unknown ways to purchase and transfers. Not Bitcoin. I appreciate your efforts to justify Bitcoin's recent price action and for the major altcoins also but I doubt it has anything to do with fundamentals and use case. Such assets are still influenced by too many factors and get into all sort of hands. I wouldn't compare them with classical ones. Times are changing and so investments. I admit that I wasn't expecting such a move and even purchased some ETH at $220 but this market is very unpredictable. Reactions are many and it's curious that most of the crypto outlets were expecting a new wave up when Bitcoin decided to do the opposite. Will now do the same and go up when everybody got bearish? We'll see. I don't see it close to $3,000 again though. Again I appreciate your efforts put up for this post. Have a good night!
