I have DOT in my portfolio and it is down 79% as of today. The amount I've put there is quite big for me. The average buy price per DOT is 25.80USD. The price of DOT today is 5.38.
So the question is what are my options to rescue the money I've put into it? Is there anything I can do or I just wait?
I am surprised by the fact that you are asking this question only now, despite the fact that the decline in the price of the coin has been going on for almost 2 years. Now the price is at its minimum values and if you are not experiencing a shortage of finances, you should wait for a bull run and possibly buy in addition DOT to reduce the average value of the coin.
