Investing in **it coins haram or halal

Hi, i'm currently trying to find an answer to this. Would i vesting in **it coins be considered haram or hala. It's like really small coins who have a day or 2 long duration at first usually and dont blow up too much. As far as i know if there is no interedt and the company are bit committing haram its fine is ehat i heard.but these coins are like small projects so u cant find out exactly what kind of activitys they have done since its a handful of people behind it. It lowkey feels like gambling how im putting in an amount, taking out in mess than an hour then repeat. However one could argue thats juts risk and reward as i could lose too. I searched online for an answer but all i find is information on alt coins or big crypto. Not **it coins in specifit.
