This. Getting involved in pump and dump groups is a great way to lose money that could have just been spent in an investment in a promising crypto. I've never been a part of a P&D group and never will be. Joining one sounds like an awful idea.

I can't think of Bitcoin and other cryptos as anything other than assets at the moment. The price fluctuations are absurd. And as so many large news outlets love to point out, there aren't many places you can directly spend Bitcoin.

Maybe in the far future things will change, but for now, I don't see it as currency.
