To tokenize your Hive SBI voting units, send 0.001 HBD per voting unit to Hive account@steembasicincome, with sbi-tokens in the transaction memo. There is a minimum transaction size of 0.005 HBD, and anything smaller will be ignored. This will transfer your voting units to Hive account@sbi-tokens and it will issue HSBIDAO tokens to you in return. If you send more HBD than is needed, the excess will be refunded to you by Hive account@sbi-tokens.
