Suggest some reliable Bitcoin wallet.

[Charles]

I need an open-source and multi-chain Bitcoin wallet, so suggest some reliable options, and also tell me what the main security concerns are to consider when I am selecting a wallet with infrequent updates or inactive developer communities.

You can explore some wallets like Exodus, Trust Wallet, Atomic Wallet, Unstoppable Wallet, or Enkrypt. A wallet that isn't updated frequently may contain security flaws that aren't addressed, which makes hacking easier. Always check to see whether the developers are still working on it and if the community is engaged.
