I have checked on Coinmarketcap there is no 100xcoin, I think the coins you have are dead coins and have no value. It could be that 100xcoin is just a pump and throw that is normal for coins that have no value, I think investing in famous and high-volume coins is much safer than investing in new coins. Not rushing in choosing coins will save us from losses, of course if you are a new investor you should learn the basics of altcoin investing.
