Trading is of 2 types rather 3 types when we come to forex, day trading, short term and long term trading, long term trading means holding your position from many days to many months, as far as crypto market is concerned day trading is a bit difficult as we do not have much fluctuation a price during any day total volume in crypto market is less as compared to Forex.

Now coming to investment in various coin, it may get huge profit but think about the people who invested in BTC at $19000, their investment now is 1/3.
while you do short term of long term trading your target price and SL should be in mind, I know a trader in crypto whose portfolio was around $50K, she was holding NPXS and now it has decreased around 10 times, its very important to have your profit level and loss level defined whenever you take the position, the most toughest thing in trading is to know the TOP and BOTTOM due to which greed and fear exists and most of the traders lose their assests, so before taking any position profit level and SL level should be well defined and when it hits any of these level one should look for a fresh position with fresh mind, position should be taken on some basis not blindly, if a trader follows these plans chances of his success are very high, last but not the least, DO NOT CONSIDER ANY FINANCIAL MARKET A QUICK MONEY MAKING MACHINE.
