Not the right time to sell right now, this looks like just a minor correction. Bitcoin will likely rise again and might even break its current ATH. If you’re not a day trader, don’t focus too much on the short term. Think long term.
Just my advice.. when Bitcoin is in a bullish phase, it’s not the time to sell unless you’ve already hit your profit target. As for me, I’m holding until the end of the year. I’ve got a feeling the market will stay bullish. Best time to sell is when the bear market starts showing signs, not now.
I've opened a spot margin position now Doge/USDT - talking about day trading...
It is fine if you practice trading too, but be sure you're not going to be selling your BTC in order to divert the funds into trading, that's going from a lesser risk to a much higher risk as the funds might be drained by trading or your portfolio reduced by a reasonable and regrettable percentage.
Just to buy and just to hold seems sensible but too boring...
Sure the right thing seems boring sometimes, but it doesn't change the fact that it is the best thing to be done. I must mention that it seems boring because you're not constantly increasing your portfolio periodically, maybe you should try out DCA and that should be enough engagement for you.
