Well maybe yes crypto trading is the fastest way to make money but only for professional I think.. For me trading cryptocurrency is really stressful, I rather to hold for long term until I make a huge profit. About profitable cryptocurrency to invest, I recommend to invest in the top coins because they are still profitable cryptos just hold cryptos for long term.
It can be but also it cannot be.
Even the professional traders, they're having hard time.
There's always the misconception when people hears out about cryptocurrencies, they're building the thought that it's a quick way to make money.
