ATH of USD value or BTC value - where will you sell?

[Daniel91]

In your place, I would think primarily about my external goals.
Of course, it is important to make profit, but bitcoin gives you the opportunity for much more than that.
Think about how much you need to achieve long-term financial freedom and sell bitcoin when you reach that level.
I suggest you change your criteria and plan for the long term.

I guess this topic should be in trading discussion because you are looking at the value and profit/loss for your trade.

It's quite simple, if you want to take out the profits in fiat and withdraw it in bank then you should sell in ATH pairing with USD.
You would easily get your profits if you pair it with fiat amount invested previously.
But if you want to reinvest and plan to keep reinvesting in future trades then you should wait for it's bitcoin value to increase.
It won't matter if the USD price will increase or decrease since you would be pairing it with BTC.
Later in future when bitcoin's price increases would be the right time to take out the profits in fiat.

But to be honest, I guess you have already missed your chance to take the profits out in BTC because when bitcoin dumped in early 2020 many altcoins were doing good.
So according to me, if you don't plan to reinvest this amount in trading then you should consider selling the altcoins for USD price.
May be later when the market undergoes a correction would be a better time to get back the bitcoins.
