Some remarks on X(6900) *

The analysis of the LHCb data on $X(6900)$ found in di-$\jpsi$ system is performed using a momentum-dependent Flatt\'{e}-like parameterization. use pole counting rule and spectral density function sum give consistent conclusions that both confining states molecular are possible, or it unable to distinguish nature $X(6900)$, if only experimental with current statistics available. Nevertheless, we lowest state di-$J/\psi$ has very likely same quantum numbers as probably not interpreted $J/\psi-\psi(2S)$ state.
