Since 3 years i started crypto trading, im not really make good profit, because when i earned alot of profit when bull market, iam not patient wait for deep price. So learn from it , when all crypto overbought so i have to quit from the market and sell all crypto to stable coin and then i buy again when the price in the deepest. And while waiting for bottomed price , i can trade on the others asset, like forex and stocks. So is better dont trade crypto when bear market to avoid loss and wait patient for the bottomed price.
Probably since you have not been making any profit since 3 years you started, you may need to take a step back and get to find out what you are actually doing wrong.
A lot of people have been in this category because they are so much in a haste to make money and you will find out that the time you could have taken to learn and practice to get it right could have been shorter than the time you will take to keep doing things over and over again without knowledge and still losing big at the same time.
I started trading in 2015, but I did not get at it immediately, I remembered after learning, how I did paper trading for a while, got to see my performance both in a bull and bear market and then I was able to gain confidence with my strategy. It only took me few months to be able to do all these, and for over 2 years now, I keep being happy I did.
