Hell we had bigger increases all for regular increases, nobody or nothing really made us buy it, we just bought it because we thought it would go up, that is the key here and we need that.
That's really all there is to it at the end of the day isn't it? We buy because we believe it will go up. Although, I sell because I need the liquidation in cash, not because I believe it will go down. When you think about it, not everyone who sells believes it's going down, more people sell because they have to, than buy because they have to.
I have always found that a very logical argument for selling. For example my mom had a health scare back in 2018, she was scared to have a heart condition, thankfully nothing came out of it but I had to cash out almost 50% of all my bitcoins during that time, paid all the hospital bills and if I kept that now it would have been about 50k dollars, but at the time it was like 8k or so, I have missed out on 42k profit because of it. However do I feel regret? I certainly do not, because I needed to do that, and knowing that my mom is healthy and doing fine right now (except for a minor hernia which is really nothing compared to heart condition) that is worth more to me than any amount of money.
If you "need" to sell because of a reason, that is fine, and that is what I do, I buy because I think it will go up, and I will only sell if I need the money and not because I believe it would go down.
