I think the best thing to do is wait for the prices or the market to be stabilized before buying. The reason is if you buy now and the prices are still going down it's a loss for you so it's better to wait than to have loss. So, you can't tell if it's a great opportunity.
Yes i agree maybe we need to wait for the value to be more higher than before. Because if you buy now then the value is getting lower or cheaper, you will be the one who suffer. So we need to wait for the right time for us to be more successful.
