I have some altcoins I bought at the ICO stage which did x pricee movement and now are dead while others are still at a stable price but I will like to make some profits at this time should I continue holding or start trading them to make instant profits what will be your advice in this situation.
Do both holding and trading. Hold those coins with potential to grow in the future and while waiting, try also to trade if you have knowledge about it. More investment, more profit to earn. About your coins from ico, if it is not worth to sell now then keep holding and wait for the market to recover.
