Cryptocurrency investment also has some risks, currently most governments in the country do not have the same protections for cryptocurrencies as for real money in bank accounts. However, if you want to succeed in changing your life, you have to take risks, because now I see bitcoin investing as having a high chance to be rich in the future.
The risk you're talking about are scams and hacks but indeed that is another risk here when it comes to investing in cryptocurrency but other than that, the main risk that everyone should worry about are from the effects of volatility. In some countries their governments don't regulate cryptos but it doesn't mean a bad thing but in fact people like this because cryptos are supposed to be independent and free from government control.
It's only the responsibility of the person that invest in cryptos and they should accept it whatever happens to their money but if they get lucky and pass all the hazards of crypto, they can become really profitable.
