The reason is low volume and utra low mcap , most of such coins are just scams and pumped by early investors in hope of making quick bucks. A lot of these coins are illiquid like even if the gains are 1000% you can't sell it in total due to very low volume.
You have to always be one very cautious with new projects as they are very high risk and reward projects and chances of scams are higher.
I saw the same problem in the Titan coin, this coin also looked scam to me. "ONLEXPA" has a few volumes but exchanges aren't good where this coin is listed. The liquidity pool of this coin is also low. Anytime the ONLEXPA price will be dumped. Other three coins should be out of topic, could be fake volume and fake pump as Titan coin.
well, finally many people have realized that the titan coin is a scam coin and the OP should have gotten a bad reputation or the safe choice is that this thread is locked by the moderator and moved to this scam session so that no one is affected by the titan coin anymore .
