Here are the lessons I learnt
1) Don't blindly trust signals, take your time to access and verify it.
2) Do your own research(DYOR), coz it gives you confidence and control.
3) FOMO and panic selling are dangerous. Rather be patient and disciplined.
4) And lastly, Don't Invest more than you can afford to loose.
Doing all this things you listed down here will really help anyone that is new into trading the spot market no doubt, but trading alt or meme coin can be very dangerous and your losses can be inevitable regardless of your research and findings concerning an asset, because meme coin and alt coin have proven to be too unreliable, due to the fact that they falls more than they rise, so it's a dangerous risk to invest heavily in it, but with Bitcoin investment your profit is certain if you are holding for a long timeframe, because no matter how it falls, it will always rally back and even better the previous price it fell from, so trading btc is much more better than this alt and meme coin you guys are risking so much on.
