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?
There is absolutely no way for you to get out of this situation other than to wait for the market to go up significantly so that the price of DOT goes up as well and then you can sell your assets, this happens in the spot market when you buy too high and then the market crashes, you will just lose value and nothing happens unless you sell them at a loss. Your only hope for now is the upcoming bull run where the prices of coins will go pretty high along with Bitcoin.
We can't really know when the bull run will start but most people are optimistic that it will be somewhere after the halving next year, but even that isn't guaranteed and it is all based on speculations and what used to happen in the past, other than that, there is no surety of a bull run at all.
