My strategy to  manage my losses is holding these tokens until the market has recovered because i know myself that i am going to lose when i would ever sell  in panic which is why you shouldnt be panicking whenever the market seems to be going down. Hokd your tokens/coins and wait for the market to recover or if you have more fiat funds, you can buy more tokens at cheap price to average your price down and when the market booms, you make more money
