you need to be able to study and know when it’s a right time for you to invest and withdraw your crypto currency.
This is the hardest part of trading, knowing the right time to buy and take profit, Ive experienced it a lot sometimes I do trades when I think the market is in dip but this is not always work as I expected. Bleeding market sometimes last for days and the only way is to DCA when you have funds left for this situation. Trading is just like a game you need not only by studying it but by being skilled and smart. If you can do this there's a high probability that you can gain more money than losing.
Every trader that knows how to trade ended up having the same problem. We buy it when it dips but then it dips even further, which is when you lose money but only if you end up selling. If you bought the dip then there could be some sort of loss but in the end you could be profiting as well at least quicker than people who buy during peak times.
Let's assume you bought at 61k recently because it dropped, and it dropped to even under 59k so right now you are in a loss, but imagine how hard would it be if you bought at 68k? That is why you are at least doing better than those people. I know that it is not a great feeling to have something that is risky like that and this is why I suggest not putting all of your money in at the same time, this way you could buy at 65k then 63k then 61k then 59k as well and could make a profit a lot quicker that way.
In short, don't go all in at one point, you need to enter at various points if you want to avoid big losses in case the coin that you are buying is going down. Also, this is the advantage of diversifying your portfolio, as you have no clue which one will hit it off in the market or will decline in the coming days, it is better to invest in different alts with promising future.
But if you are saying that you haven't lost in trading, even at one point, I don't think I will believe that. Because even expert traders can lose in trading. You can't always win on this. But of course, you can minimize your losses, depending on your strategies.
