Whether an asset is in a bubble or not is a matter of perspective. Only time knows the answer. Many altcoins are in a bubble just as many dot com companies were in the 90's internet bubble. Some had no value, others like Amazon were just in their infancy in a future world. Buy me some of that bubble! Some crypto currencies may be in a bubble, but Bitcoin being the standard bearer of crypto currencies, buy me some of that bubble. I look forward to the future.
