What coins do you trade?
regarding the loss is a risk that must be accepted, but you can minimize it, my advice to you in the future, before investing you should first learn about the coins that you will invest.
it must have been done. but sometimes the market changes all the predictions we make. we can estimate asset value growth, but who is the market condition? that makes us sometimes have to be prepared for losses, and that is natural. we just need to be patient and wait for the value to return if possible.
