You are posting on the Bitcointalk forum, so most of us are Bitcoin fans here so far. Definitely, I choose and prefer Bitcoin for holding, if need altcoin then we may go with ETH or BNB. There are many reasons behind that, first is decentralization. Bitcoin is truly decentralized and doesn't have security issues if you are holding your wallet (not an exchange wallet). An altcoin is highly risky because it would come to zero. We have seen the LUNA scam and how they make us fool actually. So believe in Bitcoin only, may trade with few good alts.
