initial capital of $ 500 with a profit of $ 30 I think that's a good thing, but maybe you should be able to sell even if you have a profit of $ 30. I think it would be better to have a little profit but it can be sustainable and try trading again with your $ 500 capital
Initial profit of 30$ is not a bad one.
Considering that your profits depend on how extensively the market runs you could make huge gains by buying at proper price and then holding it for proper time. What people make mistake in the wrong buying time - they buy at the all time high when social media is going "MOON" and get rekt or they buy the wrong coins which are pumped once every year for its bagholders to clean up their bags. Another thing that lack is patience but most get used to it nowadays as long as you are not trying to live on trading money. Buying low and selling high is the only basic thing that every person should remember if they want to "multiply" their capital.
