In the present condition of the altcoin market, it is not advisable to invest much in any altcoin at the moment even casino-based tokens like an owl, have been underperforming lately and could lead to possible loss of money if the market continues this way. Most of them have a very low trading volume at the moment.
Despite the market condition, investing in altcoin is not but investors need to invest 70% in Bitcoin while the 30% goes to the altcoin market and what I believe is important if you must invest in altcoin is making sure the coin was built on longevity, strong fundamentals, genuine utility, huge use case, and community support.
Any altcoin that has all these attributes will serve this bear market but I never support the idea of casino token investment because there's no reason for the token creation in the first place.
Everybody has his own strategy. I agree that every portfolio needs to have bitcoin in its wallet but my share is about 50%. Other than that, I have a dozens of altcoins varying from ETH, BNB to shitcoins as SHIB and a small part of casino tokens.
