The biggest mistake Ive ever made with crypto was I took a 1200$ loan in 4th quarter of 2021to invest in a meme coin that later tanked down to 70% loss, I was deluded with 100k BTC by December and also the beginning of a bigger altcoin season, I wish I listened to some advices on here instead of relying on some crazy youtubers, my own crypto journey started with huge loss i hope I will make them back some day, if you are new to crypto do not take me step.
At least no knowledge is waste, I believe you have learnt from your mistakes because the greatest mistake in life is not learning from your past mistakes. Also not all that glitters are gold. Before investing next time you have to understand the concept of timing because timing is one of the strategy wen it comes to Crypto currency.
