I think you really should study cryptocurrency more. Not to say that you or Harry Dent are wrong. Also, BTC isn't the only crypto. Tbh except for being the first crypto, it has little to offer. Compared to the likes of ETH and ADA, it's like a calculator next to computers.

Coming to applications, El Salvador made BTC legal tender and ADA is already live in Africa in the form of Atala.

Many other cryptos have real-life applications already. BAT is part of Brave browser of which I and millions of others are regular users.

A 94% crash? That's super unlikely. Even if it were to happen, it would rebound as quick
