Do not panic.
After hardfork (BTC and ETH), people will start buying altcoins back.
A little patience.

Bitcoin is growing. But this is not a flight to the moon in percentage terms in comparison with other altoin currencies.

The growth of the rate is caused by the interest of traders in the possible hardfork currency, Bitcoin Gold launch and talks around the support for SegWit2X technology. Experts predict the growth rate until October 25, after which a correction is possible.
