Whatever you said, Old Coins already have strong community behind while the newcomers mostly filled by weakhands.
Also EOS absolutely not an outdated nor overvalued coins, its still a coin which have big potential inside.
EOS never got pumped though and despite having the biggest ICO in the history of crypto market they never managed to gain as much popularity after the ICO was done and although the token ain't doing bad but never did too good either.
With the soaring prices and high transaction fees nothing from the top coins comes close to TRX because you won't be paying over $20 in fees or waiting for several days for a single confirmation so there is some usefulness for this crypto if you over look the team,vision etc
For sure and I will wish there are more projects being made on the TRC-20 chain instead of the ERC-20 because of the insanely high transaction fees there.
I will not call BCH as outdated because its a forked coin and really I got some free coins myself so I am not going to talk about them.
