That's investing, not trading. The difference between trading and investing is the simple fact that traders want to buy and sell quickly to take advantage of the price movements, if you want to buy low and sell high and do that again and again and again to get richer that's trading, whereas if you want to buy low and sell extremely high, like you can retire type of high, just do it once (or maybe few times at most) that means you are investing into it and waiting for it to be valuable.
This is why I think investing is easier, what you did was still trading, because even though you did it few times, in your mind you wanted to sell high and buy low again. For example I bought lower than you, and still holding, and will keep on holding until it reaches 500k, at that point I will retire, and I will just keep buying with some money I save, that's it, and that is investment.
What do you think about futures trading? I think about this too, not too much about maybe 3x-5x or max 10x leverage to seriously amplify my profits. This is very risky but for example with 10x leverage, you would get the profit that you aim at 50K price. And 500K would look like a 5 million. (Again, this is very risky, just stating as an idea)
A few days later, I have to admit that OP sold his BTC in a timely manner and is now watching bitcoin decline. And in the event that bitcoin continues its decline, OP will continue to eat popcorn while waiting for its planned price to buy BTC. But if the price of BTC starts to rise by updating its ATH, maybe OP will experience Fomo.
Thank you for keeping an eye on my topic. Do you know one advantage of futures trading? You can sell short, i.e. when the price falls, your profit like you were doing when the price was rising. Useful feature
I still haven't bought bitcoins but maybe will buy in the near future, waiting for what will happen on the market. And no, I won't experience Fomo because it's an enemy. You can't catch every moment because you aren't a whale and you have to analyze this from the very beginning. Only catch as many GOOD ONES as you can.
