to be fair anything is risky game, even business is risky 90% literally just went bankrupt the first year I think btc in some category fare better than conventional business but always it's the money and risk management that helps massively.
the people who plays risky game should know they should spend money where they can afford to lose and make it up easily.
the problem with most of people though, is that they just become too overconfident thinking they are different than other people and think they can come out victorious from the market, truth can never be further from that.
because i'm also sure the people who got liquidated of their perpetual trading are having the same mindset.
