What did you learn this year crypto-wise?

The meme frenzy which has taken up much of this year and is still very much alive in certain sections of social media brought a massive amount of people into the world of crypto. Some will have left immediately, others will have branched out, and a minuscule portion are likely still on a hot streak of buying before the pump and selling just prior to the dump.

Those who have branched out into the more legitimate longer term projects are apt to have had to learn quickly - there are a great many stumbling blocks even when it comes to accessing exchanges, and sending and storing crypto. These are basic but obviously essential, and people clearly struggle (I myself at the beginning used the wrong network and lost a not inconsiderable amount). So often you see a post here asking if their money is gone, and it's sad but ultimately a lesson best learnt early.

What have you learnt this year crypto-wise? Could be something extremely simple or the most complex thing you can imagine. Could help people avoid potential mistakes/ mishaps or just be funny to reflect upon.
