if you look at it from a few days ago. if you look at this since 2013, then you will see thousands of percent gains from the popular crypto.
do not see the development of prices from a few days or months, buddy. You need to do more extensive research. some circumstances may force people to sell their assets and cause a decline, but it will most likely recover.
In addition, if you look at the daily price movement, you may see a deep decline, or a high increase. however, if you broaden your horizons, then you will see really very high price increases happening year after year.
Since 2013? Better if you start counting from the beginning because some cryptos like btc have started earlier than 2013 and by that date hit they already have significant gains but its not all about gains. Crypto doesn't revolve on one side only but there is also a side where the market turns red. This what OP needs to realize. They listed a couple of coins and a few of it are not really worth it to hold in my opinion.
One of it is of course dogecoin, we all know the story of this coin. I don't wonder why this coin suffer a decline. Another coin that have gone bad is ETH. So, for me, no need to cry for their losses. We only need to worry for btc and cardano.
