Maybe so, and so what?
After all bubbles were expired, those tulips or dot.com industries or real estate or stocks market did not disappeared, right? Those industries are here and working after correction.
Yes, there is no huge profit as before, just healthy 10-15% per year, but they are still there..
so if the btc will explode, I hope that all crypto will remain, but corrected..
So what ? You cannot imagine the financial trouble people will face when it finally bursts. If it collapses and price goes to $500 or below a lot of people will become bankrupt. I think that a lot of companies will be affected as well especially those who have started to take payments in crypto.
In my opinion bitcoin is not a bubble but the current prices are heavily inflated. The main issue is that people are not using it for the purpose the developers started it. It was developed to be used as a payment medium but only few people are doing this. Everyone is interested in receiving payment in bitcoins and very few people want to spend their bitcoins.
Why do you claim that bitcoin was designed only as a method of payment? Technology blockchain, multifunctional and can be used not only as a currency. Let's see what happens in the future, and how we will use the crypto currency in our lives.
