Some people claims bitcoin is a bubblr just like as dotcom bubble in late 90's. However Nasdaq recovered after that bubble. If Bitcoin is similar we may see a similar pattern as above
BTC/blockchain is not the bubble, the sheer amount of useless copycat coins are the bubble just as the internet was not the bubble nor .com's, but the sheer amount of useless profitless .com's at the time. The "pop" will be the removal of the useless coins through regulation.
