I'm an old time trader and I've learnt a lot from my trading experience. If you can do away with greed, always use stop loss function, master your TA and also use FA to trade, avoid dumping at severe dips then you have chances of making it but with trading. It's true that when I started trading, I lost some funds following some pump channels on telegram, so I learnt the hard way never to buy coins because people are buying or because a channel made the buy call, due diligence surpasses all.
Experience is one of main factors that will contribute to good decisions of traders, beside patience, and determination. There are always two types of traders or investors: winners, and losers. People who are lack one of those characters: experienced, patient, and determinant will most likely get losses from their decisions. Buying at dips, and trying to DCA when coins drop around 20 percent to 30 percent is a good strategy to avoid losses.
