For me, altcoins are for short-term investment only and you will still find bitcoin as more reliable and efficient cryptocurrency. Altcoins are sometimes dependent on btc market, the recent drop of bitcoin to $8,000 has also affect the altcoins like ethereum.

Since then, I don't find investing and wasting time in altcoin is a good idea, unless you get free from airdrop or it is a popular altcoin that has potential like ethereum.
