It's understandable that altcoins are not back yet since bitcoin has not really have its bull run yet, we need Bitcoin to rise even higher like $15K or more to be considered it a bull run, as with that price, it's close to the ATH and this might cause some FOMO.
Then we shall see altcoins to rise after, that's my own analysis and I hope I can prove it right once BTC reaches $15K.
In any case, you need to be ready to sell your Bitcoins and start investing in altcoins. Many facts indicate that a Bitcoin correction should occur. You can earn a little money on this market movement.
