In this market most of the time experienced is what we are basing our decision-making, though patterns are available but most traders especially those who are in daily scalping, they are monitoring the movement and they understand that fluctuations might happen, and they all set both buying and selling position according to how they are following the patterns/strategy that they mostly used.
I don't know people who can do scalping for a long time. This is too complicated and my experience tells me that medium or long term trading will always bring the best results. Day trading is too tiring, because of this I make a lot of mistakes and as a result I lose money. In medium term trading it is easier to follow trends and it works better for me.
not all traders are able to successfully do daily scalping, most end up with big losses...
I am also not very able to follow the daily trend because of the many activities in the real world that take up my time so I am very happy with medium-term trading (I trade between 2 weeks to 3 weeks). a friend told me
that if you don't want to lose in trading then avoid day trading.
Not all indeed, and you are also right that most are only losing money when doing scalp trading though there are still people who work in this kind of strategy, but with that high fluctuation that you need to work from day to day it's really something that consume more of your time and worse it pollutes you with a lot of "what if" when making a mistake or choosing the wrong position when doing your trade.
Any kind of trading is profitable as long as you know your stuff, you can't earn profits if you're just a self proclaimed trader. Day trading is complicated, it's not even close to what you've said OP, I think the one you've explained was just simply a buy low sell high process. Day trading is a day trade, obviously, meaning you're selling the coins you bought in that day based on your technical analysis, which must be really accurate to gain profits.
If we are a newbie then we better start on the basic form of trading and I think that isn't day trading but day trading can be difficult and will fit for advanced users already. For an experienced trader, any kinds of trading is going to be easy for them understand but they'll probably go on the hard and risky one because the returns can be a little better.
Day trading or trading is not only profitable but I think it is the most profitable activity here in crypto as when compared to investing and others, it is because it is fast and you can add more volumes to your trade but of course you can also lose fast if you are not lucky or skillful enough.
Basic understanding give you good position when doing your trade, short or daily trading can be execute if you have that basic understanding with both risk and gained rewards, if you are willing to take your shot the call is always yours, your money means it's all on your responsibilities.
