But I trade with most popular currency and wait for the profits.But also make a research before jump

Great strategy to make handsome profits from crypto trading. I always prefer to depend on self research rather than depending on luck. When you totally depend on luck for having profits then its like gamble with luck too.
Everything is risky, trading forex or crypto is a also risky without proper knowledge and experience trading is like gambling, but still it's better to learn trade, because you can get better in trading after you got more experience,while in gambling you only rely on your luck
Risk always associate with any kind of trading. Its the way how one person's fund move to another ones hand. IMO skill and experience play a vital role behind successful trading.
