Traders use dogecoin as their asset and hold for the long term, and they will not sell their dogecoin if the price is not more than 100-150 satoshi. The last high price we already see that show dogecoin can increase to the higher price, but now, the price is back to the lowest price again. But I am sure that the price will have the time to rise again, and once that happens, traders will make their big profit again.
Never heard of traders keeping dogecoin as a long term asset to be honest, and this coming from someone who does like dogecoin a lot,,, I mean, it is a rather stable coin bitcoin-wise, price is always around current levels, and never below 10 satoshi anymore, and you never know when it can pump to 50 satoshi or more!
They don't have to tell people how long they hold dogecoin

I know my friend hold dogecoin from more than 1 years ago, after the price increase in the last 2-3 years ago. The price now more than 20 satoshi, and it is a good price to buy, so I guess many people still buy dogecoin at a price now, and that makes the queue in the buy order is big. If dogecoin gets pump, the price will be up to 50 satoshi, and sometimes, the price can be more than 100 satoshi.
