The best way to do after you suffer a big loss is to go slow and wait for the right time to recover your losses, the market goes up and down and there will always time to recover your previous losses, by now you learned a lesson about picking the right coin and buying and selling at the right time.
that means we have to hold long holdings if the assets we have go down for a long time. yes indeed it is the most normal and safe way because there is no risk of losing more assets unless the market experiences a deeper fall.
