Ethereum is in the bullmarket, I think the real peak will be around 20k$ by September, so if you hold ether don't sell now, we are still in the beginning of February and much money to be made later this year

Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis.

If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.

Try to stick to the quality coins in order to avoid scams . Binance launchpad or lauchpool projects have successful lately and made investors tons of money. Try to buy once they get listed on binance and buy when they dump.
