All the other coins designed to buy pokemon cards (XRP, XRB, TRX, IOTA) are in deep red.
these are not pokemon coins! why do you even think that?
What is generally happening? Is it a correction?
it is a dump, when whales who started this manipulative pump exit to get their massive profits out, the market starts to crash like this. it is like a cycle. they start the manipulation, pump the altcoins, newbies join in, they take the profit and start selling, price drops, newbies panic, they start dumping, market crashes.
whales move to another altcoin, newbies follow, rinse and repeat.
Should I sell the pokemon coins and put the money in the stronger one?
you should always sell coins that are losing value preferably before the dump begins and move to those that are not pumped yet or are starting to get pumped.
