If there is no reason why, then it's just a pump&dump. An organized group slowly buy in on these and then when they have accumulated enough without it being noticed...they pump in thousands of bucks to make it explode. This will get everyones attention and people who are not informed about this will think this is a solid investment. After a lot more people joined in the prices has risen dramatically and the original pumpers sell everything off and start the dump. They will exit with a big profit, leaving all second wave buyers with a pile of worthless coins and big losses... Dont fall for these kind of schemes, do some actual research and only invest in active coins with actual development and slow organic growth
