It's true that some people can actually be referred to as professional traders, but that doesn't mean they can't make the wrong call in trading. I don't usually feel any how, or should I say, I don't have any specific way I feel about any experienced trader that faces lose in their trade. The reason is because trading is kind of a skill that someone can adopt all the measures that can help them become successful traders, but the crypto market itself is so dynamic that even an expert cannot use their professional trading skill to know the market direction all the time.
In the life of a human, mistakes are inevitable, so don't ever feel that professional crypto traders or crypto experts are not supposed to experience fail trades because there is no one who cannot experience fail trades.
There are no professional or well-experienced high profile traders that can go against an unpredictable market. Yes, they can be exceptionally good with their skills and trading strategies but it cannot guarantee that they will keep winning on the market, or they will keep taking an edge over market’s volatility. That makes the market more risky to trade, and trading itself becomes riskier. Hence, we cannot tell that some can be excuse from losses because they have huge funds, or they are highly professional and high profile traders. Trading involves both winning and losing, and while others are profiting from their trades, some traders are expected to fail and lose their funds.
