It is therefore suggested that Certificated Shareholders should consider dematerialising their Shares and replacing them with electronic records of ownership. Therefore, Certificated Shareholders who have not yet appointed a CSDP or Broker will have their new Africa Bitcoin Corporation Limited shares credited to CTSE Registry pending receipt of such information by the Transfer Secretaries, together with their Documents of Title. For the avoidance of doubt, the Company will retain all ISINs and statistical, trading and reference data history for each of its existing classes of shares. The Change of Name will not result in a transfer of sector for the Company.
