Yes, I would say so. After the 2008 financial crisis, people looked towards better means of payment and an overall decentralised currency - that is sort of how bitcoin was formed. Bitcoin has done us with many benefits, however it has also fuelled the dark net with full of illegal acts, thanks to bitcoin's anonymity.
Its funny because people say it has no "real" value but these days anything you invest in with the stock market has made up values by bankers. Many businesses even operate with negative P/E and raise stupid amounts of money yet crypto is somehow in a bubble? Even the US dollar has no more backing by gold so with that analogy the USD is just as worthless.
Yes, this is very true. All currency does not have a value unless there is a physical object behind it, like gold was used as a payment form long ago. Bitcoin is better in the sense that there is a limit to how many can be mined, while the USD and any other paper currency is just being churned out at an alarming rate, creating an even bigger bubble than before.
