Although I might agree that bitcoin (as well as other cryptos) face issues that need immediate attention (fees, number of transactions, decentralization, market manipulation), I do not think that jig is up for them. They are quite big in terms of a number of traders, companies involved, mining pools, companies accepting the payment method, and organizations interested in the blockchain technology. It is here to stay. Just because its value dropped, it does not mean it will die out.
As for the rest of your post, can you clarify a bit more, I got a bit lost after "if you like being watched during sex..."?
