It is not any currency that can be good for trading, it is not any currency that can be good for buying and holding.
Many shitcoins have no purpose, they don't have a solid project, how do you expect something that doesn't have any solid project to increase in price?
For storage, none of the existing coins except Bitcoin is suitable. But those coins that I named earlier and those that you named are suitable for trading, because if you trade any coin with great volatility paired with BTC, then you can increase the volume of BTC on your wallet.
