First of all I'm not a real trader, but I like to trade to earn small amount profit.
I only use BTC/USDT pair because USDT make me easier to determine how much my coins worth after trade and most liquid stable coin, the reason why I choose BTC is I don't need to worry about it when my trading goes wrong. So if I bought Bitcoin at the peak and the price keep decreasing, I will not sell it, but I will wait for the next super cycle where Bitcoin usually break new ATH.
Keep in mind I never learn about chart, candlestick, trend etc, all of my decision come from my mood and instinct. No stop limit, no follow any signal, no watching my PC for 24/7 etc, just directly buy and sell.
Is there anyone like me here?
If it is your decision to trade bitcoin, without studying candlesticks or trends, then continue.
Because if you only trade on bitcoin, I think it will be safe. Because bitcoin already has a regular cycle, like the halving that occurs every four years. So even though I'm not very skilled at trading, I think it will be safe. But I suggest trading in bitcoins for the long term. Because if you trade in the long term, you don't need to bother thinking about trends or candlesticks, you just have to wait for the halving and the desired target price.
But if you want to go deeper into the knowledge of trading in crypto/bitcoin, I think it will be more perfect. Because to a lesser extent, if trading mainly in assets like crypto/bitcoin. Knowledge is needed first, so that it is more organized and focused on the course of your trade. Because if you only trade on bitcoin, you can still do it without having that expertise. But if you step up and want to try other crypto (altcoins), trading knowledge is very necessary.
And in essence, in my view, what you did was not wrong, it was just not quite right. Because if you trade in crypto/bitcoin, it will be easier if you already have the knowledge.
