If the alts,tokens have high price then no volume i think don't base your investing in that like example better to look how useful their alts,tokens then for sure this will grow so supply and demand will also grow so find or study if the alts,tokens are like that so do invest in that
I think inside there is a large wall that holds the price and there are no people who sell it too. so it's best to keep coins away like that unless they have a real platform and an active team so we can see more about the project. but if you are in doubt it is better to keep the project away.
