The point in terms of choice we have to be confident
I don't think so. Knowledge should be the most thing to consider before you make a choice. If you only rely on confidence, it sometimes makes you regret it since it is very risky and possible to lead you to a terrible situation. I suggest to analyze everything with your knowledge and experience first before you decide anything.
I think need knowledge and never allowing what other recommendation when trading or keep waiting with your assets, when you try for cash out looking later with moment have chance your assets increase to higher price or not. Many investors not confident and look busy for cash out without waiting next have good moment for holding with bitcoin or altcoin price going up. I think depend with your feeling which one better holding or cash out your assets.
