I will only share information based on my research and experience.

-I recently bought many coins with different prices, I was very surprised #playdapp because it had gone down to -100% without having to sell, I considered it lost, then 3 days passed I saw a 105% profit so I sold it.

From there I realized that no currency is bad, just that some are more volatile.

Be careful, never sell at a loss, please pay attention.
