I completely resonate with the mindset of "not selling," however I am currently in the phase that you described at the start of the post. But what I do is I swing trade exclusively hive, because I seem to understand this token much better than any other tokens and make sure to buy back my trading capital of hive and I sell the usdt profit to make meets end in the real world. So ina way I am also not really "selling" my crypto, but I am making full use of the crypto market movements to help me pay the bills.
Understanding how things work is a great approach, most people go into certain things without having a clue of what they are doing. Of course the market will do what it pleases it, and sometimes no matter how much we know about a specific topic, it will catch us off-guard, so we also must have a plan B for when that happens!
Yep, having a plan B is a must. Because the market is irrational and more often than not the market doesn’t follow the logic that it should.
