Firstly, this is not like buying stocks. A company's stock has a value and some sort of basis depending on demand driven by sales growth. Their is no basis to drive Bitcoin prices higher except for the speculation that prices will go up one day.

Secondly, its not a typical investment either. There is nothing tangible that you're getting out of purchasing Crypto.

Thirdly, since trading Crypto has no regulations, borders, or governing bodies, it has attracted all sorts of hackers, thieves, money launderers and scammers from all over the world.

So when you say its not for the weak and to get the hell out, that is not entirely correct. There is a judgement that people make to assess risk vs. reward before buying.

The more people who want to buy, the better the demand and higher the price, so you probably don't want to people to get the hell out.
