Yes, it is worth investing now,
why ? price of coins is starting to get higher again . for example btc now is at 9k usd . for me that price was high so i will refrain from buying right now but if you think that was small and you believe the price will increase after you buy then why not ?
but personally I believe that we should invest only in top coins, because there is much less risk of losing our money than in little-known coins.
again this depend on you . if your not risk taker and only feel comfortable on the known coins then why look for more unsure investment while others are looking for risk and reward investnment . they know what they will be doing so dont mind them
