Personally, not financial advise but it's good to hold these tokens.
To date, 8 crypto coins already meet the ISO 20022 standard: XRP (XRP), Stellar Lumens (XLM), XDC Network (XDC), Algorand (ALGO), and Iota (IOTA), Hedera Hashgraph (HBB AR), Quant (QNT) and Cardano (ADA). Two of them do not just comply with ISO 20022, they are members of the ISO 20022 standardization body.
