Hamas must not know how to use Bitcoin privately. Getting a new "core" Bitcoin wallet (via a VPN if really paranoid) gets you a new unique private encryption "key"...generate a new wallet address and use it ONLY ONCE to receive some BTC. Same for the "sender"...new wallet and only use each address once (generate a new address for each transaction). NO BTC purchases from a "KYC" exchange like "Coinbase" (& don't store any Bitcoin on an exchange...practice "self-custody"). If USD to Bitcoin is needed purchase at an anonymous marketplace like "HodlHodl", "Bisq" or "RoboSats", then "mix" that new Bitcoin at something like "CoinJoin" to "clean" the past path of the BTC you just got. With some thought/work/best practices BTC can be anonymous.
