Yes, Dogecoin is not suitable for planning in the long term because if it declines to a very large extent it will take a long time to bounce back, this is why Dogecoin is always at risk of being held in the long term.
doge has updated and improved the system carried out by management with the advantage that @elonmusk has recently done, they have the funds to be able to provide encouragement for improvements that have been made so far.
but we can't guarantee the doge's strength either but @elonmusk keeps on rattling about how he wants the doge to keep moving up. We'll see the possibility always exists because of the changes that have been made, although it may all depend on whether the investor wants to make a purchase.
