People who invest without leverage will win someday, because those people holds real coin or crypto.
And, those who trades on binance or bybit with leverage will get liquidated. Just like forex!!
I disagree with what you are saying here because in this crypto space knowledge is very much paramount, so if you have the knowledge and skills to flourish in the market, what makes you think that such person willing be at the losing end on the longer run?
Though it's a lot easier to buy an asset and hold, but not all asset guarantees success, it's only Bitcoin investment that guarantees such, the rest of other alt and shit coin alike can make you lose your hard earned money forever if you invested heavily on the wrong asset, so knowledge is the key thing here not by being a trader or an investor.
Actually nothing guarantees getting rich, you said, "All wealth does not guarantee success, but only Bitcoin investment guarantees this", I definitely do not agree with this, because Bitcoin never guarantees anything, it is a completely uncertain and volatile investment.
But yes, we can definitely talk about possibilities, Bitcoin is definitely a more promising and safer investment than all other coins. And Bitcoin investment is the most successful investment, and hopefully it will be even more big successful in the future. Although there is no guarantee of this, but it has great potential. In fact, there is no such thing as a guarantee, so we must be careful about this matter, and always invest according to the risk taking ability through proper research.
