I only invest in cryptocurrencies after I've done a research for them especially the newly listed coins that has the potential to go up in the future.
I'm actually thinking of being done with this kind of strategy upon investing to altcoins. Something like telling myself that such coins has 'potential' in the near future. I've failed many times looking at those projects but still intact with few of it.
I want to find if the team and developers are continuous to be active in improving their coin or token before investing on it. Most of the altcoins are affected by the pump and dump scheme of some big investors or whales so I have to monitor the coins often with the aid of technical indicators.
The difficulty of looking with this kind of developers is becoming harder these days. Money talks and it's usually the main reason why they have created the coin but despite of that there are still some few that's really dedicated what they've working it. Just make it a habit that before investing, research.
